Description Technical Specs
This 820 Z21 sprocket is a split construction high-quality sprocket that is manufactured for 820 series chains and features 21-teeth. It is available as a light grey PA6 thermoplastic material and can be manufactured in other materials upon request. The benefits of using a sprocket manufactured out of PA6 are that the sprocket has a high resistance to wear and dynamic loads. We keep these sprockets on the shelf as a stock bore and finished bore configurations, but we can also bore the sprocket to custom bore sizes. For more information or to get pricing and availability on the sprocket or chain please contact us and we will be happy to assist you.
