"Basic Dynamic Ratings" calculated according to AFBMA standard for "Long Rating And Fatigue Life For Ball Bearings"

Accurately machined, medium carbon steel sprockets and precision ground ball bearings are assembled to provide a heavy duty idler for the most severe conditions. The bearings are pre-lubricated and sealed to retain grease and exclude dirt and moisture. They are not re-lubricatable. The extended inner race with setscrew allows fastening to a pin or shaft without collars or spacing devices. It also provides clearance for the chain when bolting the sprocket directly to a frame member or tensioning device. A small sprocket for close quarters and a larger one for heavier service is provided in each pitch. If sizes other than those listed are required, please inquire for quotation.
