Gates tensioner pulleys provide the rotating contact surface for the accessory drive belt, working with the tensioner mechanism to support controlled belt movement. This thermoplastic pulley uses a smooth backside contact surface to match its belt contact arrangement. Gates DriveAlign replacement pulleys are designed for OE-quality fit, with bearings engineered to meet or exceed OE speed and load requirements. The range is built to withstand high underhood temperatures and exposure to dirt, salt, chemicals, and other contaminants encountered in service.
