H Series fixed-displacement axial piston hydraulic motors for open- and closed-circuit hydraulic systems: MFH33, MFH52, MFH71, MFH90 and MFH112 are designed for use in hydrostatic transmissions for travel drives or working equipment of combine harvesters, truck mixers, and other road-building and construction machinery.
Applications:
- combine harvesters;
- truck mixers;
- asphalt pavers;
- oil and gas industry equipment;
- mining equipment.
According to the applicable technical specifications (TU), Hydrosila products are not classified as dual-use products.
MFH Series hydraulic motors provide a cost-effective solution for a wide range of operating conditions. Their design is based on the Sauer Series 20 concept. Extensive modernization, carried out using Hydrosila’s many years of experience, has significantly improved the technical and operating characteristics of the main components while retaining the proven reliability and long service life of the original design concept. These motors are designed to meet the requirements of heavy-duty operation in construction, road-building and agricultural machinery.
Features:
- axial piston swashplate design;
- high hydromechanical efficiency;
- high-wear-resistance bimetallic valve plate;
- lightweight pistons for reliable operation under maximum-load conditions;
- mounting flanges in accordance with SAE standards;
- tapered roller bearings designed to withstand high radial and axial loads;
- radial or face-type shaft seal for reliable external sealing;
- integrated hydraulic components available as an option.
Hydraulic fluids: mineral and special oils with a kinematic viscosity of 30...70 mm²/s at +50 °C.
The fluids must comply with DIN 51524-2.
