Roller Chain Size Chart

Roller chains are commonly found in a large variety of power transmission, agricultural, and industrial applications. This popular type of chain provides a reliable mechanism for all kinds of different moving parts. Since its invention in 1880, conveyor, automotive, food and beverage, and farming equipment have boasted these popular and common types of chains to keep them running. This roller chain size chart will help you find the ideal size of roller chain for your replacement or OEM needs.

Functions of Roller Chains

In general, roller chains have four key functions:

• To move materials or objects from one location to another
• To transmit power
• To ensure that an action occurs consistently after the previous action over a period of time; i.e. synchronization
• To shift the direction of motion from linear to rotary

 
Roller chains have significant advantages over belt drives for these functions, as they have very little slippage or stretching across the chains even with a heavy load and are incredibly efficient and long-wearing. Roller chains are exceptional for use in a high-stress environment as they will hold up under even the most difficult conditions such as high and low temperature, or start-stop action usage. These roller chains also have a virtually unlimited shelf life as long as they are stored and maintained in the proper environment.

Sizes of Roller Chains

As you can see below in the roller chain size chart, there is a wide range of sizes that are available in this versatile chain. Single and multiple-strand roller chains are available, with different weight and tensile strength ratings based on the manufacturing requirements for their particular use. Since chains are used as a drive and as part of a conveyor system, the range of sizes can be quite significant. Smaller pitch chains are often found in light to moderate load applications while larger pitch chains are used in heavier load applications.

Roller chain sizes are standardized according to ANSI/ASME or ISO British standards, which are meant to provide interchangeability of design and dimensions for chains, sprockets, and attachments. Fortunately, you will find a wide range of options available at PEERChain.com. Roller chain specification includes key values for:

• Size
• Pitch
• Roller Width and Diameter
• Average Ultimate Tensile Strength

Sizes for ANSI/ASME standard roller chains range from 25 to 240.

Tensile and Fatigue Strength of Roller Chain

Tensile strength is one of the key measurements of roller chains and indicates specifically the one-time load capacity of a chain before it breaks. It is important to note how tensile strength is different from fatigue strength, as both are used to indicate the overall durability of a particular chain. Fatigue strength is defined as the load at which the roller chain will likely begin to fail after continuous use over a period of time.
