Rexroth A6VM Series Hydraulic Motor Replacement | A6VM115 A6VM215 High Pressure

Genlu Hydraulic proudly introduces our industrial-grade A6VM Series axial variable piston motors. Fully engineered to match Rexroth global standards, this series provides a high-performance, seamless drop-in replacement for heavy-duty mobile equipment and large-scale industrial drive systems. We specifically highlight our supply capability for high-spec units such as the A6VM115 and A6VM215 (e.g., A6VM215EP6D1P001G/71MWVOS4A210V-0).

The A6VM series utilizes an advanced bent-axis variable structure, allowing for stepless displacement adjustment to achieve constant-power or constant-torque output across wide speed ranges. Genlu guarantees 100% Drop-in Interchangeability across mounting dimensions, SAE flanges, splined-shaft specs, and control logic compared to original Rexroth A6VM assemblies. Every motor undergoes 100% full-pressure load and dynamic response testing on our digital test benches, certifying rugged, consistent performance for your most demanding heavy-duty applications.

Technical Specifications 

• Product Series: Rexroth A6VM Series Bent-Axis Axial Variable Piston Motor

Key Technical Advantages:

• Stepless Variable Regulation: Advanced variable mechanism supports wide displacement ratios (up to 1:5+), enabling real-time torque and speed adjustments for optimal system-energy efficiency.

• Superior Bent-Axis Efficiency: 40-degree inclination angle ensures elite volumetric and mechanical efficiency, significantly reducing thermal buildup during long-duration, heavy-load cycles.

• Impact Resilience: High-strength alloy housing and precision-coated rotating groups provide robust protection against transient pressure spikes and load shocks.

• Seamless Drop-in Compatibility: Strictly compliant with original A6VM dimensions, ensuring effortless integration into existing platforms without structural modifications to manifolds or piping.

Application Areas:

• Mobile Power Trains: Travel and swing drives for excavators, cranes, bulldozers, and forestry machinery.

• Marine Equipment: Heavy-duty winches, anchor handling systems, and thruster drive units.

• Industrial Transmissions: High-torque variable control for conveyors, rotary drilling equipment, and hydraulic power units.

Expert Maintenance Tips:

• Case Drain Management: Motor case pressure must be strictly maintained below 3 bar. Excessive backpressure or heat in the case drain line is a primary indicator of internal wear and warrants immediate inspection.

• Strict Filtration: A6VM series motors demand high-purity hydraulic fluid. Maintain ISO 4406 17/15/12 or better to prevent particulate contamination from sticking the variable-displacement piston.

• Control Valve Diagnostics: If the unit exhibits unresponsive speed or torque fluctuations, inspect the electrical/pilot signals for the EP control valve before attempting a complete overhaul of the main motor.
