Danfoss 51D160 & 51D110 High-Speed Variable Bent Axis Motors

Product Overview: The Danfoss 51 Series and its 51D evolved versions represent the cutting edge of hydrostatic drive technology. As bent-axis variable piston motors, they are specifically engineered to meet the demands of high-performance closed-circuit drive systems. By allowing the swashplate to swing between 0° and 32°, the 51D series provides an expansive displacement range, enabling machinery to transition seamlessly between high-torque loading and high-speed transit. This page features core models: 51D160 and 51D110. These motors are the definitive power units for self-propelled harvesters, large rollers, road milling machines, heavy-duty forestry equipment, and various specialized vehicle travel drives.

Key Technical Advantages:

• Extreme Displacement Ratio: Features infinite variability from maximum to zero (or set minimum) displacement, significantly optimizing power distribution and fuel efficiency.

• Superior High-Speed Capability: Advanced bent-axis technology allows for extremely high continuous RPMs in low-displacement modes, drastically increasing machine transport efficiency.

• Extreme Pressure Resilience: Rated for a continuous pressure of 450 Bar with peak capabilities reaching 480 Bar (7000 PSI), built to withstand intense shock loads in rugged terrains.

• Compact 51D Design: The optimized 51D architecture features a shorter axial length and flexible porting, greatly simplifying installation in tight chassis environments.

• Target Applications: Harvester travel drives, large vibratory rollers, asphalt pavers, and high-performance industrial winch systems.
