Product Description
Danfoss OMTW Series Heavy-Duty Hydraulic Wheel Motors
Product Overview: The Danfoss OMTW Series represents the pinnacle of heavy-duty orbital motors designed for wheel drives and high radial load applications, such as Feed Rollers. This category features the primary displacements: OMTW315, OMTW400, and OMTW500, with a specialized focus on precise part numbers: OMTW400 (151B3028), OMTW400 (11116528), and the extreme-duty OMTW400HD (11191766).
Utilizing Disc Valve technology combined with a specialized wheel-mounting flange, OMTW motors are engineered to be integrated deep within the drive structure. This allow their reinforced tapered roller bearings to sustain massive radial forces directly. They are the premier choice for forestry feed drives, construction propulsion, and heavy-duty conveyor systems.
Key Technical Advantages:
Superior Load Resilience: The wheel-flange design shifts the radial load center toward the motor’s internal bearings, significantly extending service life.
HD (Heavy Duty) Reinforcement: The OMTW400HD (11191766) is structurally optimized for extreme shock loads and relentless duty cycles.
High Volumetric Efficiency: The disc valve design automatically compensates for wear under pressure, maintaining peak efficiency throughout the motor’s lifespan.
100% OEM Interchangeability:
151B3028 / 11116528: Industry-standard configurations for guaranteed fit-and-function replacement.
11191766: Specially reinforced HD version for the most demanding drive applications.
