ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

Yes, roller chains are commonly used for power transmission in motorcycles. Here’s a detailed answer to the question:
Roller chains have several advantages that make them suitable for power transmission in motorcycles:
1. Efficient Power Transfer: Roller chains offer high efficiency in transmitting power from the engine to the rear wheel of a motorcycle. They have minimal power loss due to their low friction and high load-carrying capacity.
2. Compact Design: Roller chains have a compact and lightweight design, making them well-suited for motorcycles where space and weight are critical considerations. Their small size allows for efficient power transfer without adding excessive weight to the motorcycle.
3. High Strength and Durability: Roller chains are designed to withstand high loads and endure the demanding operating conditions of motorcycles. They are constructed using high-strength materials such as alloy steel and undergo heat treatment to enhance their strength and durability.
4. Flexibility and Adaptability: Roller chains can accommodate various sprocket sizes, allowing for flexibility in gear ratios and customization of motorcycle performance. This enables riders to optimize the power delivery to match their riding preferences and specific road conditions.
5. Easy Maintenance: Roller chains are relatively easy to maintain in motorcycles. Regular lubrication and tension adjustment are necessary to ensure optimal performance and prolong the chain’s lifespan. Proper maintenance practices can help prevent chain elongation, reduce wear, and minimize the risk of chain failure.
However, it’s important to note that roller chains require regular inspection and maintenance to ensure safe and reliable operation. This includes checking for proper tension, lubrication, and signs of wear or damage. It’s also crucial to follow the manufacturer’s recommendations regarding chain replacement intervals and lubrication specifications.
Overall, roller chains provide an efficient and reliable method of power transmission in motorcycles, offering durability, flexibility, and ease of maintenance.
How do roller chains handle abrasive environments?
Roller chains are designed to handle various operating conditions, including abrasive environments. Here’s a detailed answer to the question:
1. Material Selection: Roller chains are typically constructed using high-quality materials that offer good resistance to abrasion. Common materials used for roller chains include alloy steel, stainless steel, or specialized coatings that enhance wear resistance.
2. Surface Hardness: The components of a roller chain, such as the pins, bushings, and rollers, are heat-treated to achieve a high surface hardness. This hardness helps to resist wear caused by abrasive particles present in the environment.
3. Lubrication: Proper lubrication plays a crucial role in protecting roller chains from abrasive wear. Lubricants act as a barrier between the chain components and abrasive contaminants, reducing friction and minimizing wear. The lubricant also helps to flush away any abrasive particles that may come in contact with the chain.
4. Sealing and Protection: Roller chains can be equipped with seals or protective covers to provide an additional layer of defense against abrasive particles. These seals help to prevent contaminants from entering the chain and causing premature wear. Seals also help to retain lubrication within the chain, further enhancing its performance in abrasive environments.
5. Regular Maintenance: Regular inspection and maintenance are essential to ensure the longevity of roller chains in abrasive environments. This includes periodic cleaning to remove accumulated debris and checking for signs of wear or damage. Prompt replacement of worn components is necessary to prevent further deterioration and ensure reliable operation.
While roller chains are generally robust in abrasive environments, it’s important to consider the severity of the abrasion, as extremely abrasive conditions may require specialized chain materials or additional protective measures. Consulting with experts and selecting the appropriate chain design and materials based on the specific application requirements can help maximize the performance and lifespan of roller chains in abrasive environments.
What safety precautions should be taken when working with roller chains?
Working with roller chains requires following specific safety precautions to ensure the well-being of operators and prevent accidents. Here is a detailed answer to the question:
1. Personal protective equipment (PPE): Operators should wear appropriate PPE, including safety goggles, gloves, and protective clothing, to protect themselves from potential hazards such as flying debris, oil splashes, or pinch points.
2. Training and knowledge: Operators should receive proper training on the safe operation and maintenance of roller chains. They should be familiar with the equipment’s components, functions, and potential hazards associated with chain handling, tensioning, and lubrication.
3. Lockout/tagout procedures: Before performing any maintenance or repair work on machinery equipped with roller chains, proper lockout/tagout procedures should be followed to isolate and de-energize the equipment. This ensures that unexpected startup or movement of the chain does not occur, reducing the risk of accidents.
4. Inspection and maintenance: Regular inspection and maintenance of roller chains are essential to identify any signs of wear, damage, or misalignment. Operators should follow the manufacturer’s guidelines for inspection intervals and perform necessary maintenance tasks, such as lubrication, tension adjustment, and sprocket alignment, to keep the chain in optimal condition.
5. Proper tensioning: Maintaining the correct tension in the roller chain is crucial for its safe and efficient operation. Overly tight or loose chains can lead to excessive stress, premature wear, and potential chain failure. Operators should adhere to the recommended tensioning guidelines provided by the manufacturer.
6. Guarding and barriers: Installing appropriate guarding and barriers around roller chain assemblies can help prevent accidental contact with moving parts. This includes the use of chain guards, covers, or enclosures to minimize the risk of entanglement or injury.
7. Cleanliness and housekeeping: Keeping the work area clean and free from debris, oil spills, or other potential hazards is important to maintain a safe working environment. Regular cleaning of the roller chain and surrounding equipment helps prevent contamination, improves performance, and reduces the risk of slips and falls.
8. Risk assessment: Before working with roller chains, it is essential to conduct a thorough risk assessment to identify potential hazards and implement appropriate control measures. This includes evaluating factors such as load capacity, speed, environmental conditions, and specific requirements for the application.
By following these safety precautions, operators can minimize the risk of accidents and ensure the safe operation of machinery equipped with roller chains.

How do roller chains handle dusty or dirty environments?
Roller chains are designed to operate effectively in various environments, including dusty or dirty conditions. Here’s a detailed answer to the question:
1. Sealed Construction: Many roller chains feature a sealed construction, which helps to protect the internal components from dust, dirt, and other contaminants. The seals help to prevent the entry of particles into the chain’s joints and lubrication areas, reducing the risk of wear and damage caused by abrasive particles.
2. Proper Lubrication: Adequate lubrication is crucial in dusty or dirty environments. The lubricant forms a protective film on the chain’s surfaces, reducing friction and wear. It also helps to flush away and prevent the accumulation of dirt and particles. Regular lubrication maintenance is necessary to ensure the chain remains properly lubricated and protected.
3. Periodic Cleaning: In dusty or dirty environments, it is important to periodically clean the roller chain to remove accumulated debris. This can be done using compressed air or gentle brushing. Care should be taken not to use excessive force or abrasive materials that could damage the chain.
4. Proper Chain Covering: In some applications, it may be necessary to use chain covers or guards to provide additional protection against dust and debris. These covers help to shield the chain from direct exposure to contaminants, reducing the risk of accelerated wear and damage.
5. Regular Inspection: Regular visual inspection of the roller chain is essential in dusty or dirty environments. This allows for the early detection of any signs of wear, corrosion, or contamination. If any issues are identified, appropriate maintenance or replacement should be performed promptly.
It’s important to note that even with these measures, roller chains used in dusty or dirty environments will still require proper maintenance and periodic cleaning. Following manufacturer recommendations for lubrication, cleaning, and inspection will help ensure the longevity and reliable performance of the roller chain in such conditions.
How do roller chains handle static loads?
Roller chains are primarily designed for transmitting power and handling dynamic loads, which involve motion and varying forces. However, roller chains can also handle static loads to some extent. Here’s a detailed answer to the question:
1. Load Distribution: When a roller chain is subjected to static loads, the weight or force is evenly distributed across multiple rollers and pins. This helps to distribute the load more effectively and reduces stress concentrations on individual components. The load is transferred from one roller to another through the pins, ensuring a more balanced distribution.
2. Stiffness: Roller chains possess a certain degree of stiffness that enables them to resist static loads. The rigid construction of the chain, including the link plates and pins, helps maintain the integrity of the chain under static conditions. This stiffness allows the chain to support the applied load without excessive elongation or deformation.
3. Lubrication: Proper lubrication is essential for roller chains to handle static loads effectively. Lubrication helps reduce friction and wear, which can occur even under static conditions due to the weight of the load. Adequate lubrication ensures smooth movement of the chain and minimizes the risk of surface damage or increased friction during load-bearing.
4. Chain Preload: In some cases, applying a pre-load or initial tension to the roller chain can help improve its ability to handle static loads. The pre-load helps to eliminate any slack or looseness in the chain, enhancing its rigidity and reducing the potential for excessive elongation or misalignment when subjected to static forces.
While roller chains can handle static loads, it’s important to note that they are primarily designed for dynamic applications involving motion. Excessive static loads or prolonged exposure to static conditions may lead to increased wear, elongation, or deformation of the chain. In scenarios where the majority of the load is static, alternative power transmission systems or load-bearing mechanisms may be more suitable.
How do you measure roller chain wear?
Measuring roller chain wear is important to determine if the chain is still within acceptable tolerances or if it needs to be replaced. Here are the steps to measure roller chain wear:
1. Chain Elongation Measurement: Chain elongation is a common form of wear in roller chains. To measure chain elongation, you’ll need a ruler or caliper with metric units and a reference length of the chain. The reference length is typically a certain number of pitches, which is the distance from one roller to the next.
2. Select Reference Points: Choose two reference points on the chain, ideally at least 10 pitches apart. These points should be accessible and free from any significant wear or damage.
3. Measure the Distance: With the chain in a relaxed state, measure the distance between the reference points. This can be done by aligning the ruler or caliper with the rollers of the chain. Ensure the measurement is taken along the same side of the chain throughout the process.
4. Compare with the Manufacturer’s Specification: Consult the manufacturer’s specification or maintenance manual to determine the allowable elongation limit. Typically, roller chains have a maximum allowable elongation of around 1-2% before replacement is recommended.
5. Calculate Elongation Percentage: Calculate the elongation percentage by comparing the measured distance with the reference length. Subtract the reference length from the measured distance, divide the result by the reference length, and multiply by 100 to get the elongation percentage.
6. Determine Chain Condition: If the elongation percentage exceeds the manufacturer’s recommended limit, it indicates significant wear and elongation of the chain. In such cases, it is advisable to replace the chain to prevent potential failure and damage to the machinery.
It’s important to note that measuring chain wear is just one aspect of assessing chain condition. Visual inspection for signs of wear, such as pin wear, plate wear, or roller wear, is also crucial. If you notice any signs of damage or wear during the inspection, it is recommended to replace the chain, regardless of the elongation measurement.

What are the factors to consider when selecting a roller chain for an application?
Choosing the right roller chain for an application involves considering several important factors. Here’s a detailed answer to the question:
1. Load Capacity: The load capacity of the roller chain should match or exceed the maximum anticipated load in the application. Consider the weight and type of the load, as well as any shock loads or dynamic forces that may be present.
2. Speed and RPM: Determine the required speed and RPM (revolutions per minute) of the roller chain. High-speed applications may require special high-speed chains with improved heat dissipation and reduced centrifugal forces.
3. Environment: Assess the operating environment of the application. Consider factors such as temperature, humidity, dust, dirt, chemicals, and exposure to corrosive substances. Choose a roller chain with appropriate corrosion resistance, sealing, lubrication, or protective coatings based on the specific environmental conditions.
4. Length and Pitch: Determine the required length and pitch of the roller chain based on the distance between the sprockets and the desired positioning of the driven and driving components.
5. Maintenance Requirements: Consider the desired maintenance level for the application. Some roller chains may require regular lubrication, while others offer maintenance-free or self-lubricating options. Assess the availability of maintenance resources and the impact of downtime on the overall operation.
6. Compatibility: Ensure compatibility between the roller chain and the sprockets used in the application. The roller chain and sprockets should have matching pitch, tooth profile, and number of teeth to ensure proper engagement and smooth operation.
7. Certification and Standards: In certain industries, compliance with specific certifications or standards may be required. Consider whether the roller chain meets industry-specific requirements such as ISO, ANSI, or industry-specific regulations.
8. Cost and Availability: Evaluate the cost and availability of the roller chain, including factors such as initial purchase price, long-term maintenance costs, and the availability of spare parts or replacement chains.
By carefully considering these factors and consulting with experts or manufacturers, you can select the most suitable roller chain for your specific application, ensuring reliable and efficient power transmission.
How do roller chains handle lateral loads?
Roller chains are primarily designed to handle axial loads, which are loads acting in the direction of the chain’s axis. However, roller chains can also tolerate a certain degree of lateral loads, which are loads acting perpendicular to the chain’s axis. Here’s a detailed answer to the question:
1. Sprocket Alignment: Proper sprocket alignment is crucial for roller chains to effectively handle lateral loads. The sprockets must be aligned in a parallel and concentric manner to ensure that the chain tracks properly and experiences minimal lateral force. Misaligned sprockets can cause the chain to derail or experience excessive wear due to uneven loading.
2. Tolerance for Lateral Misalignment: Roller chains have some tolerance for lateral misalignment between the sprockets. This means that the chain can tolerate a slight deviation from a perfectly straight line between the sprockets. The chain’s side plates and rollers are designed to provide some flexibility, allowing the chain to adjust to minor lateral forces without significant problems.
3. Guide Rails or Flanges: In applications where lateral loads are more significant, guide rails or flanges can be employed to help keep the roller chain aligned and prevent excessive lateral movement. These additional components act as guides and help control the chain’s lateral displacement, ensuring that it remains on the sprockets and operates smoothly.
4. Chain Tension: Proper chain tension is crucial for handling lateral loads. A well-tensioned chain minimizes slack and reduces the chances of lateral movement. It helps keep the chain engaged with the sprockets and ensures that the load is evenly distributed across the chain’s width.
It’s important to note that roller chains have a primary function of transmitting power and handling axial loads. While they can handle some lateral loads within their design limits, excessive lateral forces can lead to chain derailment, increased wear, and reduced performance. Therefore, it’s essential to design the system properly, consider the anticipated lateral loads, and ensure proper alignment and tension to maintain the chain’s integrity and performance.
How do you tension a roller chain correctly?
Proper tensioning of a roller chain is crucial for its optimal performance and longevity. Here’s a detailed answer to the question:
1. Initial Installation: When installing a roller chain, it’s important to ensure that it has the correct tension from the beginning. Start by positioning the sprockets at their desired locations, ensuring proper alignment. Then, adjust the position of the shafts or tensioning devices to achieve the desired chain tension.
2. Check the Slack: After installation, check the slack or sag in the chain. The ideal tension allows for a small amount of slack to accommodate articulation around the sprockets. The slack should be uniform along the chain’s length.
3. Adjust the Tensioner: If the chain tension is too loose, adjust the tensioner to take up the slack. Tensioners can be spring-loaded devices, adjustable bolts, or idler sprockets designed to maintain proper tension. Follow the manufacturer’s instructions or recommended guidelines to set the tensioner to the appropriate position.
4. Measure the Deflection: Another method to ensure correct chain tension is to measure the chain deflection. Apply a slight force perpendicular to the chain midway between the sprockets. The deflection should typically be within a specified range, depending on the chain size and application. Refer to the manufacturer’s guidelines for the recommended deflection values.
5. Regular Inspections: Regularly inspect the chain tension to ensure it remains within the desired range. Factors such as wear, elongation, and changes in operating conditions can affect chain tension over time. Adjust the tension as necessary to maintain optimal performance.
6. Follow Manufacturer’s Recommendations: It’s important to follow the manufacturer’s recommendations for chain tensioning specific to the type and model of roller chain being used. These guidelines will provide specific instructions based on the chain’s design, load capacity, and intended application.
Proper tensioning of a roller chain helps ensure smooth operation, minimize wear, reduce the risk of failure, and extend the chain’s lifespan. It’s essential to regularly monitor and adjust the tension as needed, especially during routine maintenance checks, to maintain optimal performance and prevent potential issues.

Can roller chains be used for power transmission in mining equipment?
Yes, roller chains can be used for power transmission in mining equipment. Here’s a detailed answer to the question:
Mining equipment often requires robust and reliable power transmission systems to handle the demanding conditions and heavy loads encountered in mining operations. Roller chains have proven to be a suitable choice for power transmission in mining equipment due to their various advantages:
1. High Strength and Durability: Roller chains are designed to withstand high loads and provide reliable power transmission in challenging environments. They are made from high-strength materials such as alloy steel, which enables them to handle the heavy loads typically encountered in mining applications.
2. Resistance to Shock and Impact: Mining equipment often operates in rugged environments with frequent shock and impact loads. Roller chains are engineered to handle such conditions and can withstand the sudden changes in load and direction without compromising their performance or integrity.
3. Flexibility and Adaptability: Roller chains have inherent flexibility, allowing them to accommodate misalignment and angular movement between sprockets. This flexibility helps to ensure smooth and efficient power transmission even in applications where slight misalignments may occur due to the nature of the mining equipment.
4. Resistance to Contaminants: Mining environments can be dusty and contain abrasive particles. Roller chains are designed to resist contamination and maintain their performance even in dirty and harsh conditions. Proper sealing and lubrication can further enhance their resistance to contaminants.
5. Easy Maintenance and Replacement: Roller chains are relatively easy to maintain and replace. Regular inspection, lubrication, and tension adjustment can help ensure optimal performance and extend the lifespan of the chain. In case of wear or damage, individual chain links can be replaced without the need for replacing the entire chain, making maintenance more cost-effective.
It’s important to note that when using roller chains in mining equipment, proper selection, installation, and maintenance are crucial. Working with reputable suppliers and following recommended guidelines for chain selection, lubrication, and tensioning can help maximize the performance and longevity of the roller chain system in mining applications.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE
An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

Chain drives offer high load-carrying capacity, durability, and can operate in demanding conditions. They are commonly used in heavy machinery, agricultural equipment, and motorcycles. 5. Direct Drives: Direct drives eliminate the need for mechanical power transmission components like chains or belts. They directly connect the motor or power source to the driven equipment, providing a more efficient and compact solution. Direct drives are commonly used in applications that require high precision, such as CNC machines, robotics, and linear motion systems. When considering alternatives to roller chains, factors such as load requirements, speed, precision, environmental conditions, and cost must be taken into account. Each alternative has its own advantages and limitations, and the choice depends on the specific needs of the application.
