Product Description
Rexroth A2FM Series High-Pressure Bent Axis Axial Piston Motors
Product Overview: The Rexroth A2FM Series is a fixed displacement axial piston motor featuring proven Bent Axis technology, serving as a versatile powerhouse for hydrostatic transmissions. Renowned for its exceptional power-to-weight ratio and rugged reliability, the A2FM series is extensively used in mobile travel drives, crane winch systems, and industrial hydraulic power units. This selection features core high-performance models: A2FM16/61W-VBB030 and A2FM32/61W-VAB040. Utilizing a unique 40° bent axis geometry, the A2FM series delivers superior mechanical efficiency and precise torque output even at peak pressures up to 450 Bar.
Key Technical Advantages:
Outstanding Startup Torque: The precision-engineered spherical valve plate reduces mechanical friction during startup, ensuring smooth, “creep-free” operation even under heavy initial loads.
High Speed & High Pressure Resilience: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Its robust rotating group supports stable operation under extreme rotational speeds.
Compact Bent Axis Construction: Compared to swashplate motors, the bent axis design offers a smaller footprint for the same power output—ideal for space-constrained wheel drives or winch drums.
Extended Service Life: Equipped with heavy-duty bearings and precision piston-slipper assemblies, ensuring thousands of hours of stable operation under frequent direction changes and shock loads.
Target Applications: Rotary drilling rigs, concrete mixer drives, crane winches, excavator travel drives, and industrial press systems.
