Description Technical Specs
 
This 20BTB21H 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 20BTB21H 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 20BTB21H 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 20B roller chain, 2517 bushing, and a wide array of roller chain accessories. For more information or to get a quote on taper bushed 20BTB21H sprockets, please contact us and one of our sales team members will be happy to assist you.
