120BS21 Sprocket With 1-1/4" Finished Bore Features
120BS21 Sprocket With 1-1/4" Finished Bore Specifications
This 120BS21 sprocket features a 1-1/4" finished bore with a key-way and two set screws. It is a durable, high quality, and precision sprocket with 21 teeth. Something that is notable about this 120BS21 sprocket is that it fully meets all ANSI Standards, which insures proper contact between the #120 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. We also have stock bore sprockets, custom bore and made to order sprockets, and a full line of ANSI #120 roller chain. Fore more information, large quantities, or to get a custom sprocket please contact us and we will be happy to assist you.
