Product Description
LIC Hydraulic provides the Danfoss OMT Series (6K), the industry benchmark for heavy-duty orbit hydraulic motors. Engineered for high-load applications, the OMT family—including the powerful OMT500 (151B-3062) and the high-speed OMT250 (151B-3096)—utilizes a precision Disc Valve distribution system. This design ensures maximum volumetric efficiency and high starting torque, even at continuous pressures up to $250\text{ bar}$. With its robust construction and oversized tapered roller bearings, the OMT series is a direct-fit, high-performance solution for road construction, mining, and marine winching systems where reliability is non-negotiable.
Technical Highlights
Advanced Disc Valve Technology: Provides superior flow distribution and automatic wear compensation for long-term performance stability.
High Torque Geroler Set: Roller-equipped stator sets provide smooth operation at ultra-low speeds and exceptional power-to-weight ratios.
Reinforced Bearing Housing: Capable of handling extreme radial and axial loads, allowing for direct drive configurations without auxiliary supports.
Durable Shaft Seals: Capable of withstanding significant return line backpressure, protecting the internal components from environmental ingress.
Application Areas
Construction & Drilling: Reliable power for rotary heads and secondary winches on drilling rigs.
Road Maintenance: Feed drives for cold planers and conveyors on asphalt pavers.
Maritime Operations: High-capacity deck machinery and net haulers for commercial fishing.
Expert Maintenance Tips
Priming is Mandatory: Always pre-fill the motor housing with clean, filtered oil through the case drain port before the initial startup to prevent dry-friction damage to the Geroler set.
Monitor Case Drain Pressure: For maximum seal life, ensure the case drain line is connected directly to the reservoir with backpressure kept below $5\text{ bar}$.
Verify Mounting Alignment: Ensure precise alignment when using keyed or splined shafts to prevent eccentric loading, which is the primary cause of premature bearing wear in the 151B series.
