Rexroth A6V107 Series High-Pressure Variable Axial Piston Motors

Product Overview: The Rexroth A6V107 Series is a premier bent-axis variable displacement motor designed for heavy-duty hydrostatic transmission systems. Featuring legendary 40° Bent-Axis technology, the A6V107 allows for an extensive range of speed and torque adjustment by varying displacement without changing input flow. This featured selection highlights core high-performance configurations: A6V107HA12FS1055 (with automatic high-pressure control) and A6V107HD2GZ20720 (with hydraulic direct control). Capable of operating at continuous pressures up to 400 Bar, these motors are the definitive power source for excavator travel drives, rotary drilling heads, dozer transmissions, and large industrial mixer drives.

Key Technical Advantages:

• Extended Variable Displacement Range: Seamlessly adjusts from maximum to minimum displacement, delivering exceptional starting torque and high-speed travel capabilities.

• Advanced Control Options: * HA12 (Automatic Control): Automatic high-pressure adjustment that optimizes displacement based on load pressure for maximum system efficiency.

  • HD2 (Hydraulic Direct Control): Precision displacement adjustment proportional to pilot pressure, offering superior control sensitivity.

• Superior Power Density: The bent-axis architecture enhances mechanical efficiency while outputting massive power within a compact installation footprint.

• High-Pressure Resilience & Durability: Rated for 350-400 Bar (5800 PSI) continuous and up to 450 Bar (6500 PSI) peak, equipped with reinforced bearings for the harshest environments.

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