Our E20B21 sprockets are made with reliability and performance in mind, so we use high-quality carbon steel (CS) and have the sprocket precision cut to ensure maximum performance and wear life. Besides the stock bore we also can supply these sprockets with a specific plain or finished (has key-way and set screws) bore size. We also offer upgrades on our triple E20B21 sprockets such as black-oxide coatings and heat-treated hardened teeth, hardened teeth increases the durability and wear life of the sprocket while a black oxide coating will create an “anti-rust” coating on the sprocket. Besides the 21 tooth sprocket, we also stock a high-quality 20B-3 roller chain & sprocket and a wide array of roller chain & sprocket accessories.
