Description
Metric idler sprockets can be found for Metric Roller Chain and are made to guide and move the roller chain in a specific direction. Because they are an idler it needs the energy and “pull” of a sprocket drive. Utilizing a top-quality bearing or material inside an idler sprocket results in less friction for your set-up that allows for better energy transfer, while making use of less energy. Our metric and ANSI idler sprockets are designed to last longer and perform better than the other sprockets.
