This 085B8 sprocket with a stock bore is a metric roller chain sprocket manufactured under ISO and British Standard 228. Our 085B8 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 085B8 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 8 tooth sprocket, we also stock a high-quality 085 roller chain and a wide array of roller chain accessories.
