Rexroth A6VM Series High-Pressure Bent-Axis Variable Motors

Product Overview: The Rexroth A6VM Series stands as the definitive powerhouse for heavy-duty hydrostatic transmission systems. Featuring advanced 40° Bent-Axis technology, these motors provide an extensive displacement adjustment range, enabling a broad spectrum of speed and torque control without altering the input flow. This featured selection highlights core configurations: A6VM80HA1/63W-VAB01000A and A6VM107HA1/63W-VZB378. Renowned for their exceptional power density and Series 63 reliability, the A6VM series is the premier choice for crawler travel drives, rotary drilling rigs, bulldozer transmissions, and large-scale industrial mixing systems.

Key Technical Advantages:

• HA1 Automatic Control: Automatically adjusts displacement based on load pressure. It increases displacement for higher torque under heavy loads and decreases it for higher velocity during light-load operation.

• Extended Variable Displacement: The bent-axis design allows seamless adjustment from maximum to minimum displacement (approaching zero), providing superior acceleration and high-speed operation.

• Extreme Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) and peak pressures up to 450 Bar, engineered to withstand intense shock loads in harsh environments.

• High Power Density: The compact bent-axis architecture outputs massive power within a minimal installation footprint while effectively reducing internal friction.

• Target Applications: Excavator travel and swing drives, heavy-duty crane winches, TBM propulsion systems, and marine deck machinery.
