NEW: MPTA S1i-2023 – Roller Chain and Sprocket Terminology
The transmission of mechanical power between parallel shafts can be achieved through the use of a roller chain and roller chain sprockets. This informational bulletin provides a listing of commonly used terms as compiled by the members of the Chain and Sprocket industry. It contains definitions of these terms as they apply to Roller Chain and Roller Chain Sprockets.
MPTA and the American Chain Association
MPTA is the custodian of these documents, originally prepared by the American Chain Association (ACA). MPTA makes them available as a service to the industry.
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.
Engineered Class Chain Connect Disconnect
The purpose of these Chain Connect-Disconnect Instructions is to provide the chain user with recommended methods for assembling and disassembling chain.
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.
