A roller chain, known also in the industry as transmission chain is commonly used to transmit power from a geared motor drive. Machinery speed can then be altered by varying the size of the drive sprockets used.

Roller chain is produced as simplex, duplex, triplex up to mega plex from some of the leading suppliers in the world. Roller chain can be supplied in various materials from mild steel chain to Nickel Plated or in stainless steel for high strength agricultural chain. Other roller chain is also available which can be run lube free known as specialist lubricated chain. Roller chains are available across a range of applications and even to suit the most demanding of environment.

Leaf chains generally have greater tensile strength than roller versions, and run over sheaves rather than sprockets. They are commonly used as counterweight for machine tools, elevator and oven doors, and fork lift truck masts, spinning frames and similar lifting or balancing applications.
