Sauer Danfoss 51V Series Motor | 51V080, 51V110, 51V060 | 480 Bar Bent Axis Variable Motor

Sauer-Danfoss 51V Series Bent Axis Variable Displacement Motor

Product Overview: The Sauer-Danfoss 51V series is synonymous with high performance and efficiency in hydrostatic drive technology. Utilizing a sophisticated Bent Axis design, this series features core displacement sizes including 60cc (51V060), 80cc (51V080), and 110cc (51V110). Engineered for both open and closed hydraulic circuits, the 51V series handles peak pressures up to 480 Bar. Models like the 51V080RS1N…0700 provide an exceptional displacement ratio (up to 5:1) and superior low-speed torque, making them the premier choice for road rollers, pavers, and heavy-duty forestry machinery.

Key Technical Advantages:

• High-Efficiency Bent Axis Design: The bent axis architecture offers lower mechanical friction and superior self-priming characteristics compared to swashplate designs, maintaining peak volumetric efficiency across the entire speed range.

• Ultra-High Pressure Capability: Rated for continuous operation at 450 Bar (45 MPa) with peak cycles reaching 480 Bar, ensuring structural integrity under extreme load spikes.

• Extensive Displacement Range: Supports smooth modulation from zero to maximum displacement, allowing machinery to transition from high-torque climbing to high-speed travel without gear changes.

• Precision Control Integration (HZB/BEG):

  • Features diverse control options including two-point, proportional, and pressure-related controls.

  • Configurations like HZB1 / BEG5 ensure seamless integration with the machine’s electronic management systems for rapid response.

• Rugged & Compact Construction: The optimized housing design offers maximum strength with reduced weight, facilitating layout flexibility within compact vehicle chassis.
