Rexroth A2FM Series High-Pressure Axial Piston Motors

Product Overview: The Rexroth A2FM Series is a fixed displacement axial piston motor utilizing advanced Bent-Axis technology, designed for hydrostatic drives in both open and closed circuits. Renowned for its superior power density and high starting torque, the A2FM is an industry-leading solution for diverse hydraulic applications. This selection features core high-performance models: A2FM28/61W-PPB030, A2FM45/61W-PPB030, and A2FM56/61W-VAB027. Capable of stable operation at peak pressures up to 400 Bar, the A2FM series is the premier choice for construction machinery, mobile cranes, plastics processing, and forestry equipment.

Key Technical Advantages:

• Efficient Bent-Axis Engineering: The unique 40° bent-axis design reduces physical dimensions while maximizing volumetric and mechanical efficiency, resulting in less heat generation.

• Extreme Pressure Stability: Rated for 350 Bar continuous and 400 Bar peak pressure, it is engineered to handle instantaneous pressure spikes during startup or heavy-load cycles.

• Outstanding Speed Performance: Optimized for high-speed operation with precision balancing, ensuring smooth performance across the entire RPM range with ultra-low noise levels.

• Robust & Durable Construction: Equipped with reinforced bearings and high-precision rotating groups, ensuring an extended service life in harsh environments (high temperatures/dusty conditions).

• Target Applications: Crawler travel drives, winch hoisting mechanisms, fan drive systems, auxiliary power units, and industrial extrusion equipment.
