08B roller chain sprockets are made for metric 08B roller chain and is manufactured in accordance with ISO, DIN, and BS228 standards. All of our sprockets are precision made from higher-top quality metal, and the vast majority of them are black oxide coated, and have hardened tooth on tooth counts thirty or considerably less. Some thing crucial to know notice is that on tooth counts 31 and up hardened enamel make small to no efficiency boost, this is why it is not common.
