Rexroth A2FM Series High-Pressure Axial Piston Motors

Product Overview: The Rexroth A2FM Series is a fixed displacement axial piston motor featuring the legendary Bent-Axis technology, specifically designed for hydrostatic drives in both open and closed circuits. Renowned for its exceptional mechanical efficiency and compact installation dimensions, the A2FM is a global industry standard. This selection features core high-performance models: A2FM125/61W-VAB010, A2FM160/61W-VAB010, and the optimized A2FM200/63W-VAB010. Capable of delivering stable torque at peak pressures up to 400 Bar, these motors are the premier choice for heavy crane winches, mixer drives, excavator swings, and drilling power heads.

Key Technical Advantages:

• Proven Bent-Axis Engineering: The unique 40° bent-axis design drastically reduces motor size while ensuring superior self-priming capabilities and mechanical efficiency.

• Extreme Pressure Capability: Rated for 350 Bar (35 MPa) continuous and 400 Bar (40 MPa) peak pressure, engineered to handle instantaneous shock loads in heavy-duty environments.

• Full Lifecycle Reliability: Optimized with reinforced bearing and sealing systems for harsh construction site conditions, maintaining an extended service life even under frequent reversal cycles.

• High-Speed Performance: Precision dynamic balancing ensures smooth operation across the entire RPM range with ultra-low noise and minimal vibration.

• Target Applications: Concrete mixer drum drives, drilling rig power heads, large crane winch systems, mining machinery, and recycling equipment.
