Rexroth A6V Series Hydraulic Motor | A6V80 A6V107 A6V160 | A6V80HA2

LIC Hydraulic provides the Rexroth A6V Series, the global benchmark for high-pressure bent-axis variable displacement motors. Specifically engineered for demanding industrial and mobile applications, the A6V family—ranging from 28cc to 250cc—utilizes a specialized bent-axis design that offers superior power density and efficiency compared to swashplate alternatives. The featured model, A6V80HA2FZ1055, is equipped with the HA (High-Pressure Automatic) control, allowing the motor to increase its displacement automatically as load increases, providing maximum torque when needed most. Rated for continuous operation at 350 bar (5075 PSI), the Rexroth A6V series ensures high reliability for winches, travel drives, and rotary actuators.

Technical Highlights

• Bent-Axis Superiority: Offers a larger swashplate angle for an increased range between minimum and maximum speeds/torques.

• HA Automatic Control: The integrated HA2 logic senses load pressure to adjust displacement in real-time, optimizing energy consumption and machine performance.

• High Starting Torque: Engineered for high volumetric efficiency during startup, critical for heavy lifting and excavation.

• Rugged Construction: Built with high-strength rotary components to withstand the intense pressure spikes of mining and construction environments.

Application Areas

• Lifting & Cranes: Main and auxiliary winches for tower cranes and crawler cranes.

• Drilling & Foundation: Power heads for rotary drilling rigs and directional drills.

• Mobile Propulsion: Travel drives for heavy-duty wheeled and tracked vehicles.

Expert Maintenance Tips

• Mandatory Case Priming: Before initial startup, the motor housing must be pre-filled with filtered hydraulic oil to prevent immediate failure of the rotating group.

• Monitor Case Drain: Ensure the case drain line is correctly sized and routed back to the tank to keep backpressure below 2 bar, protecting the high-pressure shaft seal.

• Filtration Vigilance: To ensure the longevity of the precision-engineered bent-axis pistons, maintain fluid cleanliness at ISO 18/16/13.
