Fixed Displacement Axial Piston Motors BF20 Series

BF20 Series fixed-displacement bent-axis axial piston hydraulic motors: MBF20.56, MBF20.80 and MBF20.107 feature a high-strength cast-iron housing and are designed for hydraulic systems of mobile machinery and equipment operating under heavy loads. They can be used in both open- and closed-circuit hydraulic systems.

Applications:

• construction machinery;
• agricultural machinery;
• forestry machinery;
• material-handling equipment;
• municipal machinery;
• mining equipment;
• oil and gas industry equipment;
• railway equipment.

According to the applicable technical specifications (TU), Hydrosila products are not classified as dual-use products.

The motors feature a fixed-displacement bent-axis axial piston design. The 40° bent-axis angle provides a compact design and high operating performance.

The high-strength cast-iron housing provides structural strength and reliable operation under high hydraulic loads and temperature variations. The bimetallic cylinder block offers high wear resistance, while tapered roller bearings allow the drive shaft to withstand significant radial and axial loads.

Tapered pistons with compression rings and the design of the rotating group ensure stable motor operation over a wide speed range. Versions with integrated hydraulic components are available for specific applications.
