28B Metric Roller Chain Sprockets

28B roller chain sprockets are manufactured for metric 28B roller chain and is manufactured in accordance with ISO, DIN, and BS228 standards. All of our sprockets are precision manufactured from high-quality steel, and the majority of them are black oxide coated, and have hardened teeth on tooth counts 30 or less. Something important to know note is that on tooth counts 31 and up hardened teeth make little to no performance increase, this is why it is not standard.
