Rexroth A2FM Series High-Pressure Fixed Piston Motors

Product Overview: The Rexroth A2FM Series is the performance cornerstone of global heavy machinery drives. As a definitive Bent-Axis fixed displacement motor, it is engineered specifically for hydrostatic drives in both open and closed circuits. This featured selection includes high-performance specs: A2FM160/61W-VAB100F-S and A2FM200/63W-VAB027V, which are critical rotary and hoist components for heavy equipment like the Trinity 2600 Crane. With its superior power-to-weight ratio, the A2FM series delivers stable RPM and torque under extreme load cycles.

Key Technical Advantages:

• Extreme Pressure Capability: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, perfectly suited for instantaneous high loads during crane lifting.

• Bent-Axis Efficiency: The optimized bent-axis design minimizes internal friction, maintaining high volumetric efficiency even at high rotational speeds.

• Optimized for Cranes: Engineered for seamless integration with gearboxes in Trinity 2600 Crane systems, providing smooth starting torque and precise positioning control.

• Rugged Construction: Features reinforced bearings and premium sealing systems, significantly extending service life in harsh outdoor environments like ports and construction sites.

• Target Applications: Crane slewing mechanisms, hoist winch drives, heavy excavator travel, marine deck machinery, and material handling systems.
