Description Technical Specs
This 28B21 sprocket with a stock bore is a metric roller chain sprocket manufactured under ISO and British Standard 228. Our 28B21 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 28B21 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 28B roller chain and a wide array of roller chain accessories. For more information or to get a quote on 28B21 sprockets, please contact us and one of our sales team members will be happy to assist you.
