Rexroth A10FM Series Piston Motor | A10FM45 A10FM58 A10FM63 | Fixed Displacement Motor

The A10FM Series axial piston fixed displacement motors from Chengyuan Hydraulic are high-performance driving components fully compatible with Rexroth Series 52/53 standards. These motors are engineered for high-speed continuous operation, offering an exceptionally compact design and superior volumetric efficiency. For core models like the A10FM45/52W, we utilize reinforced swashplate supports and high-hardness valve plate sets. Every motor undergoes 100% simulated full-load condition testing before shipment to ensure smooth startup stability and consistent torque output at 280 bar rated pressure, guaranteeing 100% original-place interchangeability.

Key Technical Advantages:

• High-Speed Performance: The A10FM utilizes lightweight piston assemblies and optimized porting, allowing for higher maximum speeds than equivalent gear motors. This is critical for fan drives or sweeping systems requiring high linear speeds.

• Superior Starting Torque Efficiency: By precision-grinding the contact surfaces between piston slippers and the swashplate, we significantly reduce the static friction coefficient. The motor delivers high torque from a standstill, ensuring reliable startup under load.

• Symmetrical Bidirectional Rotation: Models with the “W” code feature a symmetrical valve plate design, ensuring identical pressure drop and output efficiency in both clockwise and counter-clockwise directions.

• Integrated Valve Block Capability: The rear cover is designed to accommodate integrated relief or anti-cavitation valves. For high-inertia loads like large fans, this feature prevents cavitation and over-pressure spikes during rapid deceleration.

Application Areas:

• Agriculture & Sanitation: Cooling fan drives for harvesters and rotating brush drives for road sweepers.

• Construction Machinery: Drive units for small vibratory rollers and auxiliary power for concrete pumps.

• Industrial Systems: Automated conveyor drives and auxiliary power for hydraulic winches.

Expert Maintenance Tips:

• Case Drain Pressure Management: The A10FM requires an external drain line. Ensure it is plumbed directly to the tank, and the case pressure does not exceed 10 bar to maintain shaft seal integrity.

• Initial Priming Protocol: Before initial startup, the motor housing must be filled with clean hydraulic oil through the highest drain port to prevent damage to the piston slippers during dry-start conditions.

• Viscosity & Temperature Control: Recommended operating viscosity is between 16-36 mm²/s. For extreme high-temperature environments, use premium anti-wear hydraulic oil meeting ISO 4406 18/16/13 standards.
