  • 400M: This model is equipped with a 2-stage cast aluminum gearbox with machined helical gears, offering a minimum roller length (RL) of 25.59 inches and power ranging from 3 to 20 HP. It comes with standard thermal protection switches and is available with a stainless steel exterior for corrosive or high-pressure washdown environments. The 400M is ideal for applications such as portable crushing & screening plants, mobile conveyors, steel production, iron & salt mining, cement & concrete production, open sand & gravel pits, and wood chip handling.

  • 400H: The 400H 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 27.56 inches and power ranging from 3 to 20 HP. Like the 400M, it includes standard thermal protection switches and is available in a stainless steel exterior for corrosive environments. The 400H is particularly suited for hopper feeders, portable crushing & screening plants, mobile conveyors, steel production, cement & concrete production, open sand & gravel pits, and wood chip handling.

Both models are perfect for industries that require a compact and high-performance drive in demanding environments, offering reliability, low maintenance, and excellent adaptability.
