In some cases it means that we actually develop and manufacture very special chain & sprocket types for 1 particular customer. In order to be able to do so, 3 things are important:40BS20 sprocket featured a 1-3/8″ finished bore with a key-way and 2 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 #40 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. We also offer stock bore sprockets, custom bore and made to order sprockets, and a full line of #40 roller chain & sprocket.
