Rexroth A6VM140 Series High-Pressure Variable Displacement Motors

Product Overview:

The Rexroth A6VM140 Series is a bent-axis variable axial piston motor, expertly engineered for both open and closed-circuit hydraulic systems. Renowned for its elite power density and expansive displacement ratio, the A6VM140 balances speed and torque by precisely adjusting displacement without altering pump flow. This page features high-precision models: A6VM140HD2D (Hydraulic Proportional Control) and A6VM140EP2 (Electric Proportional Control). These motors are the premier choice for crawler excavator travel drives, large crane winches, rotary drill rig power heads, and heavy-duty forestry machinery.

Key Technical Advantages:

• Expansive Control Range: Features a high displacement ratio ($V_{max} / V_{min}$), allowing the equipment to deliver massive torque under heavy loads and achieve high RPMs during rapid transit.

• Precision Control Modules:

  • HD2D (Hydraulic Proportional): Delivers linear displacement adjustment via pilot pressure for smooth and refined handling.

  • EP2 (Electric Proportional): Features integrated solenoid technology for seamless integration with modern electronic control systems.

• Extreme Pressure Resilience: Rated for a continuous operating pressure of 400 Bar with peak capabilities reaching 450 Bar, built to withstand intense shock loads.

• Versatile Interface Options: High-strength shaft options like VZB017B and VZB027FPB ensure a robust and reliable connection to various planetary gearboxes.

• Target Applications: Heavy excavator travel drives, crane winch systems, milling machines, and specialized construction machinery.
