Description Technical Specs
This D40BS21H sprocket with 1-3/16" finished bore is a durable, high quality, and precision double sprocket with 21 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 #40-2 double roller chain 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. D40BS21H sprockets with a 1-3/16" finished bore are supplied with a standard key-way and two set screws. If you don't see the finished bore size you need and are needing custom bore sprockets, we have the capability of providing them within a fast lead time and at a really competitive price. For more information, or a custom sprocket quote please contact us and we will be happy to assist you.
