Flat Belt Pulley

Flat belt pulleys are used in transmission systems that are driven by flat belts, typically high-speed, low-power applications in textiles, paper making, and office machinery such as computer printers. Our flat belt pulleys and flat belt idler pulleys have a molded crown, which helps to center the belt, prevent rubbing against the outside flanges, and provide support under the center of the belt, where there is the most stress. The crown also helps to keep the belt on the flat belt pulley (belts tend to move to the tightest position). In some cases, our flat belt drive includes a tracking sleeve or other mechanism for keeping the belt on the flat pulley.
