Description Technical Specs
This 40BS70 sprocket features a 1-1/8" finished bore including a key-way and two setscrews. It is a durable, high quality, and precision sprocket that fully meets all ANSI Standards which insures proper contact between the #40 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 offer stock bore sprockets, custom bore and made to order sprockets, and a full line of #40 roller chain. Fore more information, large quantities, or to get a custom sprocket please contact us and we will be happy to assist you.
