Danfoss 51V Series Variable Bent Axis Axial Piston Motors

Product Overview: The Danfoss 51V Series features high-performance bent-axis variable displacement piston motors, specifically engineered to meet the rigorous demands for speed and torque regulation in modern mobile machinery. This series covers the full range from 51V060 to the massive 51V250. Leveraging unique bent-axis technology, the 51 Series achieves smooth and extensive displacement variation while maintaining elite power density. This page features the high-precision configuration: 51V250 RC8N HZB1…. These motors are the industry choice for tracked vehicle drives, excavator travel systems, forestry machinery, road construction equipment, and heavy-duty crane winches.

Key Technical Advantages:

• Extensive Variation Capability: The bent-axis design allows displacement to be adjusted from maximum to minimum (up to a 5:1 ratio), providing a wider speed range without mechanical gear changes.

• Superior Efficiency: Optimized spherical piston technology reduces mechanical friction, ensuring elite mechanical and volumetric efficiency throughout the entire displacement range.

• High-Speed Performance: Supports exceptional self-priming and operational speeds, making it the premier choice for high-speed drive applications.

• Versatile Control Logic: * HZB1 Control: Two-point hydraulic control for rapid displacement switching.

  • Available with electric proportional control and various pressure override options.

• Target Applications: Rotary drilling rig heads, concrete pump drives, combine harvester transmissions, and large-scale material handling equipment.
