Danfoss 51V Series Variable Bent Axis Axial Piston Motors

Product Overview: The Danfoss 51V Series features premium variable displacement bent-axis piston motors, specifically engineered for modern heavy-duty mobile machinery. Leveraging unique Bent Axis technology, the 51V series achieves seamless displacement adjustment from maximum to zero while maintaining elite power density. This category covers the full spectrum from 51V060 to the massive 51V250, highlighting the precision configuration: 51V080 RF1N HZB1 BHG5DDH074AANN. These motors are the definitive power source for crawler drives, excavator travel systems, forestry harvester heads, and high-speed winch drives.

Key Technical Advantages:

• Extensive Speed Modulation: The bent-axis architecture supports a massive variable range, allowing machinery to transition smoothly from high-torque climbing to high-speed travel without mechanical gear shifts.

• Superior Mechanical Efficiency: Optimized spherical piston technology minimizes internal friction and leakage, ensuring high power conversion efficiency even at maximum operating pressures.

• High-Speed Capability: Fluid paths optimized for high rotational speeds make it the industry benchmark for high-speed hydraulic drive systems.

• Versatile Control Logic (HZB1):

  • HZB1 Control: Hydraulic two-point control for rapid and reliable switching between displacement settings.

  • RF1N: Relates to specific shaft configurations and mounting flange standards.

• Target Applications: Rotary drilling rigs, concrete pump trucks, heavy-duty cranes, pavers, and material handling equipment.
