Rexroth A2FM56/61W Axial Piston Motor | A2FM10 to A2FM56 | High Pressure Bent Axis Motor

LIC Hydraulic’s Rexroth A2FM Series is a premium range of fixed displacement bent axis axial piston motors. Renowned for its superior Bent Axis Technology, the A2FM delivers unmatched starting torque and mechanical efficiency compared to swashplate designs. The featured model, A2FM56/61W-VAB027, offers 100% seamless interchangeability with original Bosch Rexroth components. Each unit undergoes 100% simulated load testing to guarantee peak performance integrity under continuous pressures of up to 400 bar.

Key Technical Advantages

• High-Performance Bent Axis Design: The 40° bent axis geometry provides the highest power-to-weight ratio in the industry, making it ideal for compact spaces requiring high torque.

• Superior Starting Efficiency: Minimized friction between pistons and drive shafts ensures a high mechanical starting torque, allowing smooth operation under full load.

• Heavy-Duty Tapered Roller Bearings: Specifically engineered to withstand significant radial and axial forces, ensuring longevity in mobile propulsion and winch applications.

• One-Piece Rugged Housing: The reinforced housing is designed to manage peak pressure spikes of 450 bar, providing safety and durability in open and closed-loop circuits.

Application Areas

• Construction Machinery: Excavator swing drives and crawler travel motors.

• Lifting & Cranes: Primary/secondary winch motors and tower crane slewing mechanisms.

• Material Handling: Conveyor drives and port machinery.

• Industrial Drives: Mixers, metal scrap shears, and metallurgical equipment.

Expert Maintenance Tips

• Mandatory Priming: The motor case must be pre-filled with clean hydraulic oil via the highest drain port (Port L) before initial startup to ensure lubrication of the rotating group.

• Case Drain Pressure: A dedicated drain line is required. Ensure case pressure remains below 2 bar to protect the high-pressure shaft seal from premature failure.

• Fluid Viscosity Management: Maintain operating viscosity within the 16 to 36 mm²/s range. Low viscosity can lead to increased internal leakage and excessive wear on the bent axis components.
