A6VM Series Axial Piston Variable Motor (A6VM28-A6VM160, A6VM80HD1/63W-VZB020A, R987235263)

1. Variable Displacement & Speed Flexibility

   Equipped with an advanced swashplate adjustment mechanism, the A6VM series enables stepless regulation of displacement and output speed to match real-time system demands. This design allows the motor to switch seamlessly between high-torque low-speed and low-torque high-speed modes, maximizing operational efficiency and adapting to diverse working conditions—from heavy-load material handling to rapid positioning tasks.
2. Robust Construction for Harsh Environments

   Built with high-strength alloy cylinder blocks, precision-machined pistons and hardened steel components, the A6VM series withstands extreme operating pressures, shock loads and abrasive working environments (such as mining sites and construction fields). The motor’s sealed structure effectively prevents dust, debris and hydraulic fluid contamination, ensuring long-term stable operation with minimal wear.
3. Wide Model Range for Versatile Applications

   The A6VM product line covers diverse power requirements to suit different equipment types: compact models (A6VM28, A6VM55) are ideal for light-to-medium duty machinery like small excavators and agricultural harvesters; mid-range models (A6VM80, A6VM107, A6VM115) cater to medium-sized loaders and concrete mixers; and heavy-duty models (A6VM140, A6VM160) power large mining trucks and industrial crushers. The A6VM80HD1 variant is optimized for high-pressure continuous operation, delivering enhanced durability for stationary industrial equipment.
4. Direct Replacement & Interchangeability

   Following standardized dimension and interface specifications, the A6VM series (including the A6VM80HD1/63W-VZB020A model with OE number R987235263) serves as a drop-in replacement for original equipment motors. It requires no additional modification during installation, significantly reducing equipment downtime and maintenance costs for operators.
5. Low Noise & Energy-Saving Performance

   Precision manufacturing processes minimize internal friction and mechanical resonance, resulting in ultra-low noise and vibration levels during operation. This not only improves operator comfort but also reduces energy loss, lowering overall system operating costs. The motor’s high volumetric efficiency further ensures optimal use of hydraulic fluid, avoiding unnecessary power waste.
