RULMECA®'s 12.64" diameter Motorized Pulley range offers three different performance levels for bulk applications. The RULMECA® 320L Light-Duty Motorized Pulley is designed for regular and continuous operating conditions. It is advisable to rubber lag these Pulleys to grip the belt and limit belt tension. Typical applications include portable conveyors, and cross belts in mobile crushing and screening equipment. NB: The 320L should not be used for low-speed, high-torque feeder conveyors.

The RULMECA® 320M Medium-Duty Motorized Pulley is designed for tough and harsh operating conditions including crushing and screening applications, asphalt, cement, and concrete plants.

The RULMECA® 320H Heavy-Duty Motorized Pulley features a 3-Stage Gearbox, larger shafts, and stronger bearings which enable the 320H to provide low-speed at high-torque and handle irregular loadings in harsh operating conditions.
