40BS20 Sprocket With 1-7/16" Finished Bore 4 Bolt Flange Bearings HCFJT206-20 Bearing DimensionsThis 40BS20 sprocket featured a 1 7 16" finished bore with a key way and two set screws. It is a durable, high quality, and precision sprocket with hardened teeth. Sprockets that have hardened teeth last longer and are much more durable than those that don't.
