A6VM Series Axial Piston Variable Motor (A6VM28/A6VM55/A6VM80/A6VM107/A6VM140, R902216502, A6VM140DA2/63W-VZB0170HB)

1. Direct Replacement for Rexroth A6VM140 SeriesFollowing the exact dimensional and interface specifications of the original Rexroth A6VM140 motor, the A6VM140DA2/63W-VZB0170HB (with OE reference R902216502) is a seamless drop-in replacement. No additional modifications to mounting brackets, hydraulic connections, or control systems are required, drastically cutting equipment downtime and maintenance costs for operators.
2. Variable Displacement & Stepless Speed RegulationEquipped with a precision swashplate control mechanism, the motor enables stepless adjustment of displacement and output speed to match real-time system demands. It switches smoothly between high-torque low-speed (ideal for heavy lifting and material handling) and low-torque high-speed (perfect for rapid positioning tasks) modes, maximizing energy efficiency and operational flexibility.
3. Wide Model Range for Versatile ApplicationsThe A6VM series caters to diverse power requirements across equipment types:

• Compact models (A6VM28, A6VM55): Suited for light-to-medium duty machinery like small excavators, agricultural harvesters, and compact loaders.

• Mid-range models (A6VM80, A6VM107): Ideal for medium-sized equipment including concrete mixers, road rollers, and forklifts.

• Heavy-duty model (A6VM140): Powers large-scale machinery such as mining trucks, rock drills, and industrial crushers.

4. Robust Construction for Harsh EnvironmentsBuilt with high-strength alloy cylinder blocks, hardened steel pistons, and a sealed housing structure, the motor withstands extreme operating pressures, shock loads, and abrasive working conditions (e.g., dusty mining sites, rugged construction fields). Its advanced sealing system prevents hydraulic fluid contamination and external debris ingress, ensuring long service life with minimal wear.
5. Low Noise & Energy-Saving PerformancePrecision machining minimizes internal friction and mechanical resonance, resulting in ultra-low noise and vibration levels during operation. This enhances operator comfort while reducing energy loss. The motor’s high volumetric efficiency ensures optimal hydraulic fluid utilization, lowering overall system operating costs.
