Accurately machined, medium carbon steel sprockets and precision surface ball bearings are assembled to supply much duty idler for the most severe conditions. The bearings are pre-lubricated and sealed to maintain 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 right to a frame member or tensioning gadget. A small sprocket for close quarters and a larger one for heavier services is provided in each pitch. If sizes apart from those listed are required, make sure you inquire for quotation.
