Triple E12ATB21 Sprocket (Taper Bushed)

This E12ATB21 sprocket is a metric taper bushed style roller chain sprocket manufactured under ISO and British Standard 228. and is made to accept a 2517 taper bushing. Our E12ATB21 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 E12ATB21 sprockets such as black-oxide coatings and heat-treated hardened teeth, though we often have these specific sprockets with those features already added right off the shelf. Besides the 21 tooth sprocket, we also stock a high-quality 12B-3 roller chain, 2517 bushings, and a wide array of roller chain accessories.
