60BS21 Sprocket With 1-3/16" Finished Bore 4.5" Stock Bore Part #:SBRFB204-12This 60BS21 sprocket featured a 1 3 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. Something else that is notable about this sprocket is that it fully meets all ANSI Standards, which insures proper contact between the #60 roller chain and sprocket thus preventing premature wear
