Danfoss OMT Series Heavy-Duty LSHT Orbital Hydraulic Motors

Product Overview: The Danfoss OMT Series is the high-performance benchmark in the orbital motor industry. Utilizing advanced Disc Valve technology, the OMT range is specifically engineered to withstand high pressures and continuous heavy-duty cycles. This category features the core sizes OMT250, OMT315, and OMT500, with direct cross-references to OEM part numbers: 151B3009, 151B3005, and 151B3020. Integrated with heavy-duty tapered roller bearings, these motors handle massive radial and axial loads directly, making them the premier choice for mobile crushers, rotary drill heads, marine winch systems, and heavy-duty forestry harvesters.

Key Technical Advantages:

• Elite Volumetric Efficiency: Disc valve technology compensates for wear, ensuring consistent efficiency and torque output throughout the motor’s service life.

• Heavy-Duty Bearing Support: Robust axial and radial load capacities allow for direct mounting to wheels or high-tension chain drives.

• Extreme Condition Resilience: Optimized distribution geometry and high-strength Geroler sets ensure stable operation under frequent reversals or high shock loads.

• OEM Technical Decoding:

  • 151B3009: Corresponds to the OMT315 standard model with specific shaft and flange configuration.

  • 151B3005: Corresponds to the OMT500 size, delivering the highest torque in the series.

  • 151B3020: Relates to specific technical variants (e.g., specialized seals or porting arrangements).
