Rexroth A6VM80 Motor | A6VM80HD1/63W, A6VM80HA1R1 | Axial Piston Variable Motor

Rexroth A6VM80 Series High-Pressure Axial Piston Variable Motors

Product Overview: The Rexroth A6VM80 Series is a premier power solution for global construction machinery and heavy-duty industrial drive systems. As a definitive bent-axis variable displacement motor, it delivers exceptional power density across an expansive speed range. This featured selection includes two elite configurations: A6VM80HD1/63W-VZB010B (Hydraulic Proportional Control) and A6VM80HA1R1/63W-VZB0170PA (Automatic High-Pressure Control). Engineered to handle extreme stress cycles, the A6VM80 is the top choice for excavator travel and swing drives, road planers, crane winch systems, and hydrostatic transmissions.

Key Technical Advantages:

• Dual Control Modalities: HD1 offers precise hydraulic proportional regulation where displacement follows pilot pressure seamlessly. HA1 features automatic high-pressure regulation, adjusting displacement based on load pressure without external signals to optimize fuel efficiency.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, ensuring ultimate reliability in harsh environments.

• Bent-Axis High Efficiency: Optimized piston and cylinder designs provide maximum mechanical efficiency, ensuring smooth and massive torque output even under low-speed, heavy-load conditions.

• Rugged Series 63 Architecture: Reinforced bearing systems and specialized seals offer superior resistance to vibration and mechanical shock, significantly extending service intervals.

• High Integration Capability: The compact design allows for direct integration within planetary gearboxes or wheel drives, drastically saving installation space.

• Target Applications: Crawler travel propulsion, heavy-duty crane winch drives, TBM drives, and high-pressure industrial hydraulic circuits.
