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..

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):
| Pitch (inches) | Pitch expressed in eighths |
ANSI standard chain number |
Width (inches) |
|---|---|---|---|
| 1⁄4 | 2⁄8 | 25 | 1⁄8 |
| 3⁄8 | 3⁄8 | 35 | 3⁄16 |
| 1⁄2 | 4⁄8 | 41 | 1⁄4 |
| 1⁄2 | 4⁄8 | 40 | 5⁄16 |
| 5⁄8 | 5⁄8 | 50 | 3⁄8 |
| 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.

Can a mechanical chain be used for vertical lifting applications?
Yes, a mechanical chain can be used for vertical lifting applications in certain circumstances. However, it is essential to consider several factors to ensure safe and efficient lifting operations. Here are some detailed explanations:
A mechanical chain used for vertical lifting is typically referred to as a “lifting chain” or “hoisting chain.” Lifting chains are designed and manufactured to meet specific safety standards and regulations to ensure their suitability for lifting applications.
When considering the use of a mechanical chain for vertical lifting, the following factors should be considered:
- Chain Design and Strength: Lifting chains are specially designed and constructed to withstand the stresses and forces involved in lifting operations. They are typically made from high-strength alloy steel and feature specific chain configurations, such as grade, pitch, and diameter, to provide the necessary load-bearing capacity.
- Load Capacity and Working Load Limit (WLL): It is crucial to select a lifting chain with an appropriate load capacity for the intended lifting application. The working load limit (WLL) specifies the maximum load that the chain can safely lift under normal operating conditions. Exceeding the WLL can result in chain failure and potential accidents.
- Attachments and End Fittings: Lifting chains often incorporate end fittings or attachments, such as hooks, shackles, or master links, to facilitate connection to the load and lifting equipment. These attachments should be selected and used in accordance with applicable safety standards and guidelines.
- Safety Factors and Regulations: Lifting operations involving mechanical chains are subject to various safety regulations and standards, such as those set by occupational safety organizations and government authorities. These regulations specify requirements for equipment selection, inspection, maintenance, and safe operating practices. It is important to adhere to these regulations to ensure the safety of personnel and proper lifting operations.
- Inspection and Maintenance: Regular inspection and maintenance of the lifting chain are essential to ensure its continued safe and reliable operation. Visual inspections, load testing, and verification of compliance with safety standards should be performed at regular intervals by qualified personnel.
It is crucial to consult with qualified professionals and adhere to applicable regulations and guidelines when using a mechanical chain for vertical lifting applications. They can provide specific guidance based on the requirements of the lifting task, ensuring the selection and safe use of the appropriate lifting chain.
