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 #40-2 double roller chain & sprocket and sprocket thus preventing premature wear or breakage. This sprocket is also black oxide coated which increases resistance to the environment and will prevent early rust build up. D40B12H sprockets with a stock bore is supplied with a standard 1/2″ inside diameter hole with no keyway or set screws and can be easily machine bored to custom sizes. If you are needing custom bore sprockets, we have the capability of providing them within a fast lead time and at a really competitive price.
