28CTB57 Sprocket (Taper Bushed)

This 28CTB57 sprocket is a metric taper bushed style roller chain sprocket manufactured under ISO and British Standard 228. and is made to accept a 4040 bushing. Our 28CTB57 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 28CTB57 sprockets such as black-oxide coatings and heat-treated hardened teeth, though hardened tooth sprockets are typically not utilized on tooth counts past 30. Besides the 57 tooth sprocket, we also stock a high-quality 28B roller chain, 4040 bushings, and a wide array of roller chain accessories.
