Silent Chain Connect Disconnect

There are a number of industrial silent chain manufacturers in the United States and each produces different types of silent chain. Chains from different manufacturers differ in design and therefore should not be interconnected, nor should their parts be interchanged. These instructions illustrate and describe the procedures for connecting and disconnecting some of the most common silent chains. For information on chains not shown here consult the manufacturer.

Roller Chain Connect Disconnect

Since roller chain performance is dependent on interference fits of component parts, this Connect-Disconnect instruction has been developed to guide the individual working on the chain in the techniques that are considered by chain manufacturers to be safe while protecting the design integrity of the roller chain.

Roller Chain Power Ratings

The American Chain Association (ACA) first published power ratings for roller chain in 1961. After much research and analysis, the American Chain Association (ACA) has developed improved power ratings for ANSI Standard roller chains. They represent a notable upgrade to the original power ratings.
