Danfoss H1B 250 Cc Motor | H1B-250-A-A-L2-BB | Bent Axis Variable Motor

Danfoss H1B Series 250cc Bent Axis Variable Displacement Motor

Product Overview: The Danfoss H1B-250 is an industry-leading bent-axis variable hydraulic motor engineered for heavy-duty drive requirements in closed-circuit systems. As a key component of the H1 series, this motor features a massive 250cc displacement. Featured model H1-B-250-A-A-L2-BB… (Part No. 83044050) utilizes a 32-degree bent-axis technology to deliver superior power density and an expansive speed range. It is the premier choice for primary drives in large rotary drilling rigs, crawler cranes, forestry harvesters, and specialized heavy-duty mobile machinery.

Key Technical Advantages:

• Superior Power Density: The compact bent-axis architecture allows for massive torque output within a minimal footprint, supporting rated pressures up to 450 Bar and peak cycles at 480 Bar.

• Wide Displacement Ratio: Enables seamless transition from maximum to minimum displacement (even zero), providing exceptional tractive effort and high-speed travel capabilities.

• High-Precision L2 Control Logic:

  • L2 Control: Ensures highly responsive performance and accurate pressure compensation across varying load conditions.

• Reinforced Bearing & Sealing (NP-050): Specifically designed for rugged off-highway environments with high vibration and shock loads, significantly extending fatigue life and sealing integrity.

• 100% OEM-Standard Compatibility:

  • The complex smart code (e.g., PF-VS-FS-S) defines specific proportional electric controls, speed sensor interfaces, and flange standards, ensuring a direct drop-in replacement for original equipment.
