Rexroth A2FM Series High-Pressure Bent-Axis Fixed Displacement Motors

Product Overview: The Rexroth A2FM Series is the undisputed performance standard for drive systems in industrial and mobile machinery. Utilizing the legendary 40° Bent-Axis technology, these fixed displacement motors are engineered to deliver exceptional volumetric efficiency and starting torque in both open and closed circuits. This featured selection highlights two core heavy-duty configurations: A2FM80/61W-VZB020 and A2FM90/61W-PBB027. Renowned for their compact Series 61 design, the A2FM series is the premier choice for crawler travel drives, rotary drilling rigs, concrete pump mixers, and heavy crane winch systems.

Key Technical Advantages:

• Elite Bent-Axis Engineering: Compared to swashplate designs, the 40° bent-axis architecture offers superior self-priming, higher speed limits, and outstanding mechanical efficiency.

• Extreme Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, built to withstand intense transient shock loads in grueling conditions.

• Reinforced Bearing System: Equipped with heavy-duty optimized rolling bearings that handle massive axial and radial forces, significantly extending service intervals in harsh environments.

• Compact & Universal Mounting: The Series 61 design provides a minimal installation footprint, easing integration into tight compartments while maintaining excellent industry-standard interchangeability.

• Target Applications: Excavator travel drives, TBM propulsion systems, forestry harvesters, and material handling cranes.
