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 #120 roller chain & sprocket and sprocket which prevents premature wear or breakage. This sprocket is also black oxide coated which increases resistance to the environment and will prevent early rust build up. 120R21 sprockets are bored to accept a R1 type taper bushing, which we also stock with a wide range of bore sizes. We also offer sprockets with finished bore configurations, and if you are needing a custom bore sprocket we can do those as well within a fast lead time and at really great prices.
