Rexroth A2FM Series High-Pressure Axial Piston Fixed Motors

Product Overview: The Rexroth A2FM Series is a fixed displacement motor featuring a proven Bent-Axis design, serving as the global benchmark for hydrostatic transmissions. Renowned for its exceptional power-to-weight ratio and compact dimensions, the A2FM series is extensively utilized in mobile machinery travel drives, crane winch systems, and industrial hydraulic equipment. This selection covers the full displacement spectrum, including compact models A2FM28, A2FM32, A2FM45, mid-range A2FM56, A2FM63, A2FM107, and heavy-duty sizes A2FM125, A2FM160, A2FM180. Core configurations featured include A2FM32/61W-VBB040 and the 61W-VPB05 sequence. Utilizing 40° bent-axis technology, these motors deliver superior volumetric efficiency even at peak pressures up to 450 Bar.

Key Technical Advantages:

• Outstanding Startup Performance: The spherical valve plate design significantly reduces mechanical friction during startup, ensuring smooth, “creep-free” operation even under heavy initial loads.

• High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Reinforced bearing systems are built for extended service life in harsh environments.

• Comprehensive Displacement Range: Precise grading from 23 cm³ to 180 cm³ allows engineers to select the exact match for specific torque and speed requirements.

• Ultra-Compact Bent-Axis Design: 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.

• Target Applications: Rotary drilling heads, concrete mixer drum drives, crane winches, excavator travel drives, and industrial press hydraulic sources.
