Danfoss 51 Series Bent Axis Variable Displacement Motors

Product Overview: The Danfoss 51 Series represents the cutting edge of bent-axis hydraulic motor technology. As variable displacement units, the 51 Series (covering 51D060, 51D080, 51D110, and 51D160) are engineered for both open and closed circuit applications. These motors allow for extreme output speed and torque flexibility by adjusting displacement without changing input flow. Their advanced bent-axis design ensures maximized mechanical efficiency across the entire operating range. This category features high-precision models like RD2N HSA2 CEE1…. The 51 series is the premier choice for combine harvester travel, heavy-duty drill rig rotation, TBM propulsion, and various tracked vehicle systems.

Key Technical Advantages:

• Expansive Displacement Ratio: Features a 5:1 displacement capability, allowing machines to balance heavy-duty climbing (high torque) with rapid transit (high speed).

• Superior Speed Capabilities: Optimized bent-axis piston technology allows for significantly higher continuous speeds than standard motors, increasing work cycle efficiency.

• Versatile Control Options: Supports Pressure Compensated (PC) control, two-position electric control, and hydraulic control, perfectly matching different load-sensing systems.

• High Pressure Resilience: Rated for operating pressures up to 480 Bar (7000 PSI), maintaining reliability under the most grueling heavy-load conditions.

• Integrated Thermal Management: The housing includes ports for integrated flushing valves to effectively manage heat buildup in closed-loop systems, extending seal life.
