Rexroth A6VM107 Series Variable High-Pressure Axial Piston Motors

Product Overview:

The Rexroth A6VM107 Series is a premier variable displacement axial piston motor utilizing the legendary Bent-Axis technology, specifically engineered for hydrostatic drives in both open and closed circuits. Renowned for its exceptional power-to-weight ratio and broad displacement range, the A6VM is the industry benchmark for heavy-duty drive solutions. This featured selection includes the core 107cc displacement models: A6VM107HA2 (Automatic Pressure-Related Control), A6VM107HA2T (with Override), and A6VM107EZ2 (Electric Proportional Control). Capable of handling peak pressures up to 450 Bar, the A6VM107 is the premier choice for crawler travel drives, mobile cranes, rotary drilling rigs, and heavy-duty winches.

Key Technical Advantages:

• Superior Control Range: The bent-axis design allows for wide, infinite adjustment from maximum to zero (or minimum) displacement, optimizing performance between high torque and high speed.

• Diverse Control Options:

  • HA2/HA2T (Automatic Pressure Control): Automatically adjusts displacement based on system pressure, delivering high torque for heavy loads and high speed for light travel.

  • EZ2 (Electric Proportional Control): Enables remote digital control via proportional solenoids, ensuring precise and agile dynamic response.

• Extreme Pressure Capability: Rated for 400 Bar (40 MPa) continuous and 450 Bar (45 MPa) peak pressure, engineered to withstand intense load fluctuations.

• Proven Bent-Axis Reliability: The classic 40° bent-axis engineering ensures top-tier mechanical and volumetric efficiency with minimal heat generation.

• Target Applications: Construction machinery travel drives (crawlers), marine and truck-mounted crane winches, drilling rig power heads, and large material handling systems.
