Accurately machined, medium carbon steel sprockets and precision surface ball bearings are assembled to supply a heavy duty idler for the the majority of serious conditions. The bearings are pre-lubricated and sealed to maintain grease and exclude dirt and moisture. They aren’t re-lubricatable. The extended inner race with setscrew enables fastening to a pin or shaft without collars or spacing products. In addition, it provides sprockets clearance for the chain when bolting the sprocket right to a body member or tensioning gadget. A little sprocket for close quarters and a larger one for heavier services is supplied in each pitch. If sizes apart from those listed are necessary, please inquire for quotation.
