Accurately machined, medium carbon steel sprockets and precision ground ball bearings are assembled to supply a heavy 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 enables fastening to a pin or shaft without collars or spacing gadgets. It also provides clearance for the chain when bolting the sprocket directly to a body member or tensioning device. A little sprocket for close quarters and a larger one for heavier program is provided in each pitch. If sizes apart from those listed are required, please inquire for quotation.
