Rexroth A6VE Series Motor | A6VE80 A6VE107 A6VE160 | A6VE80HD6/63W-VAL027A-E

The Rexroth A6VE Series from LIC Hydraulic is a premier axial variable displacement piston motor with a specialized “Plug-in” cartridge design. By allowing the motor body to be directly integrated into gearboxes, the A6VE series significantly reduces the axial length of the drive train. Models like the A6VE80HD6/63W-VAL027A-E provide high-efficiency power delivery with sophisticated hydraulic control options. We guarantee 100% mechanical interchangeability and perform 100% variable displacement response and full-load torque testing on every unit, ensuring industrial-grade performance at $400\text{ bar}$ continuous pressure.

Technical Configuration Details

• Displacement Sizes: From $28\text{ cc/rev}$ to $250\text{ cc/rev}$ (e.g., A6VE80, A6VE160).

• Control Type (HD6): Hydraulic proportional control for seamless displacement adjustment.

• Design: Cartridge-type bent-axis axial piston for maximum power density.

• Pressure Rating: Continuous $400\text{ bar}$ ($5800\text{ psi}$); Peak $450\text{ bar}$ ($6500\text{ psi}$).

• Integration: Specifically designed for integration into planetary gearboxes or final drives.

Key Technical Advantages

• Space-Saving Cartridge Design: The specialized mounting flange allows for deep integration into machinery, making it the ideal choice for final drives where space in the undercarriage or wheel hub is limited.

• Wide Displacement Ratio: Offering a large ratio between $V_{max}$ and $V_{min}$, the A6VE enables machines to achieve high torque at low speeds for working modes and high speeds for traveling modes.

• Bent-Axis Efficiency: The proven $40^\circ$ bent-axis technology ensures high mechanical and volumetric efficiency throughout the entire displacement range, minimizing heat generation.

• Simplified Plumbing: Integrated control valves (including flushing and relief valves) reduce the need for external manifolds, simplifying the overall hydraulic circuit and minimizing potential leak points.

Application Areas

• Undercarriage Drives: Track drives for excavators, asphalt pavers, and drilling rigs.

• Wheel Drives: Final drives for wheel loaders and material handlers.

• Gearbox Assemblies: Directly integrated power source for mobile planetary reducers.

• Heavy Duty Propulsion: Winch drives and specialty vehicle transmissions.

Expert Maintenance Tips

• Housing Priming: Due to its integrated mounting, ensuring the motor case is completely filled with oil is critical. Use the highest available drain port to bleed all air to protect the high-speed rotating components from dry friction.

• Control Calibration: For HD6 proportional control models, verify that the pilot pressure matches the expected displacement curve. Jerky shifting is often a symptom of air in the pilot lines or contaminated control orifices.

• Static Seal Integrity: The O-rings on the cartridge flange are the only barrier between your hydraulic system and the gearbox oil. Always replace these seals with high-specification Viton versions during reinstallation to prevent fluid cross-contamination.
