28B25 Sprocket With Stock Bore

This 28B25 sprocket with a stock bore is a metric roller chain sprocket manufactured under ISO and British Standard 228. Our 28B25 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 28B25 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 25 tooth sprocket, we also stock a high-quality 28B roller chain and a wide array of roller chain accessories.
