Fixed axial-piston motors in swashplate design for closed and open circuits hydraulic systems. They are used as a part of hydrostatic drive transmission or operating equipment of combines, road and construction mobile machines.
Application:
- Combines
- Concrete mixer trucks
- Asphalt pavers
- Oil-and-gas machines
- Mining machines
The hydraulic motors MFH series are a cost competitive solution for a variety of application conditions.The design is based on the Sauer 20 series. The large-scale modernization, carried out on the basis of long-term experience of the company, allowed to increase considerably technical and operational characteristics of units and kept the famous reliability and durability. These motors meet the requirements of heavy-duty applications in construction, road and agricultural machinery.
Characteristics:
- Swashplate design.
- High hydromechanical efficiency.
- Bimetal bearing plate has a high wear-resistance.
- Lightweight piston provides reliability in operation at high speeds.
- Mounting flanges according to SAE.
- Tapered roller bearings enable the hydraulic motor to withstand high radial and axial loads.
- Shaft seals (face seal or lip seal) provide reliable external tightness.
- Built-in hydraulic equipment optionally.
