ANSI Standard Roller Chain

– All PEER roller chains incorporate solid rollers enhancing rotation on the bushing while reducing impact loads on the sprocket tooth during operation.

– All chain components are heat treated to achieve maximum strength and greater wear resistance.

– All PEER roller chain is pre-loaded during the manufacturing process to minimize initial elongation.

– Hot dipped lubrication ensures 100% lubrication of all chain components to extend wear life and reduce maintenance costs.
