Rexroth A6VM107 Motor | A6VM107HA1, A6VM107HA1TB | Axial Piston Variable Motor

Rexroth A6VM107 Series High-Pressure Axial Piston Variable Motors

Product Overview: The Rexroth A6VM107 Series is the definitive power solution for heavy-duty mobile machinery drives worldwide. Featuring a legendary bent-axis design, this variable displacement motor is engineered for both open and closed circuits, delivering exceptional power density across an expansive speed range. This featured selection focuses on two elite automatic high-pressure control models: A6VM107HA1/63W-VZB370A-S and A6VM107HA1TB/63W-VZB37800A-S. With the specialized HA1 automatic control, these motors adjust displacement based on system pressure without external signals, making them the premier choice for excavator travel drives, rotary drilling rigs, pavers, forestry equipment, and heavy-duty winch systems.

Key Technical Advantages:

• Intelligent HA1/HA1TB Automatic Control: Features automatic high-pressure regulation that adjusts displacement based on load requirements, ensuring the machine always operates within its optimal power band.

• Bent-Axis High Efficiency: The classic bent-axis architecture provides superior starting torque and volumetric efficiency, ensuring smooth, consistent power output even at ultra-low speeds.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, managing sudden overloads and harsh environments with ease.

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

• SK/S Specialized Configuration: Includes optimizations for specific industrial standards (like SK specs), providing enhanced compatibility and installation flexibility.

• Target Applications: Crawler travel propulsion, heavy-duty crane winches, TBM (Tunnel Boring Machine) drives, and construction rotary drives.
