28BTB21H Sprocket (Taper Bushed)

This 28BTB21H sprocket is a metric taper bushed style roller chain sprocket manufactured under ISO and British Standard 228. and is made to accept a 3020 bushing. Our 28BTB21H 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. We also offer upgrades on our 28BTB21H 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, 3020 bushing, and a wide array of roller chain accessories.
