12BTB21H Sprocket (Taper Bushed) Features
12BTB21H Sprocket (Taper Bushed) Specifications
This 12BTB21H sprocket is a metric taper bushed style roller chain sprocket manufactured under ISO and British Standard 228. and is made to accept a 2012 taper bushing. Our 12BTB21H 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 12BTB21H 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-1 roller chain, 2012 bushings, and a wide array of roller chain accessories.
