Danfoss 51V Series High-Pressure Variable Bent Axis Motors

Product Overview: The Danfoss 51V Series features premium variable displacement bent-axis piston motors, engineered for the most demanding mobile machinery applications. Leveraging advanced Bent Axis technology with a maximum swivel angle of 22°, the 51V series achieves seamless displacement modulation from maximum to zero, offering an exceptional speed ratio without mechanical gear shifts. This category highlights the core 110cc and 160cc sizes, featuring precision configurations: 51V110-RF1N-HSA2… and 51V160-RF1N-EPA5…. These motors are the definitive choice for crawler drives, rotary drilling rig heads, concrete pump agitators, and heavy-duty forestry machinery.

Key Technical Advantages:

• Elite Modulation Range: The bent-axis architecture supports a displacement ratio of up to 5:1, enabling smooth transitions from high-torque startup to maximum travel speeds.

• High-Pressure Resilience: Rated for a continuous pressure of 450 Bar with peak capabilities reaching 480 Bar (7000 PSI). Reinforced synchronization ensures longevity under intense shock loads.

• Advanced Control Options:

  • HSA2 / CHE1: Integrated hydraulic control and pressure compensation for smooth and rapid displacement shifting.

  • EPA5 / ACD0: Electric proportional control options with sensor feedback for enhanced automation and precision.

• Superior Efficiency: Optimized spherical piston technology minimizes internal friction, maintaining elite volumetric efficiency even at high rotational speeds.

• Target Applications: Crawler travel drives, winch systems, road milling machines, and forestry harvester heads.
