Rexroth A2FM Series Fixed Displacement Bent Axis Hydraulic Motors

Product Overview: The Rexroth A2FM Series is the definitive standard in hydraulic power transmission. As a fixed displacement axial piston motor featuring a bent-axis design, the A2FM efficiently converts hydraulic energy into mechanical rotational power. Known for its robust construction and exceptional pressure resistance, this series is suitable for both open and closed-circuit systems. This category covers a broad spectrum from the compact A2FM32 to the ultra-heavy-duty A2FM355. These motors serve as the vital power heart for crane winch mechanisms, mixer drum drives, excavator slewing, TBM propulsion, and heavy industrial presses.

Key Technical Advantages:

• Elite Power Density: The classic bent-axis architecture allows the pistons to operate stably at extremely high speeds, delivering massive power output within a minimal installation footprint.

• Extreme Pressure Resilience: Rated for a continuous operating pressure of 400 Bar (5800 PSI) with peak capabilities reaching 450 Bar, built to withstand heavy shock loads.

• Superior Startup Efficiency: High mechanical and volumetric efficiency throughout the entire speed range ensures smooth and powerful performance during heavy-load starts.

• Universal Compatibility: A wide variety of shaft options (keyed, splined) and mounting flanges (ISO, SAE, DIN) ensure a perfect match with various gearboxes and pump stations.

• Low Maintenance Design: Optimized spherical valve plates and reinforced bearings significantly extend the motor’s service life in harsh environments.
