The Motorized Pulley 320M and 320H models are designed to provide compact, reliable, and low-maintenance drive solutions for a variety of demanding industrial applications. Both models feature a robust gearbox system housed in a compact carbon steel shell with a 12.64-inch outer diameter and an IP66/67 enclosure class, ensuring protection against dust and water.
320M: Equipped with a 2-stage cast aluminum gearbox and machined helical gears, the 320M offers a minimum roller length (RL) of 19.69 inches and powers ranging from 1 to 15 HP. It includes standard thermal protection switches and is available in a stainless steel exterior for corrosive or high-pressure washdown environments. This model is ideal for portable crushing & screening plants, mobile conveyors, portable air separators for sand, iron & salt mining, cement & concrete production, open sand & gravel pits, and more.
320H: The 320H features a 3-stage cast iron gearbox with machined helical gears, providing enhanced performance for slow-speed, high-torque applications. It has a minimum roller length (RL) of 21.65 inches and powers ranging from 1 to 15 HP. Like the 320M, it includes thermal protection switches and is available with a stainless steel exterior for corrosive applications. The 320H is particularly suited for hopper feeder conveyors, portable crushing & screening plants, portable frac sand plants, mobile conveyors, and other heavy-duty operations.
Both models are perfect for industries requiring compact, reliable, and efficient drives in tough environments.
