Danfoss OMTS Series Bearingless LSHT Hydraulic Motors

Product Overview: The Danfoss OMTS Series is a specialized line of bearingless hydraulic motors engineered for highly integrated drive systems. By eliminating the internal bearing housing, the OMTS series allows for direct embedding into planetary gearboxes or machine housings. This category features core displacements: OMTS200, OMTS250, and OMTS315, with a focus on the industry-standard part number 151B0420.

Utilizing advanced Disc Valve technology, the OMTS series delivers exceptional power density within an ultra-short envelope. It is the premier choice for heavy-duty track drives, winch gearboxes, forestry harvesters, and industrial mixing drives.

Key Technical Advantages:

• Ultra-Compact Short Design: The bearingless architecture significantly reduces the installation length, making the entire drive unit more compact and lightweight.

• High Volumetric Efficiency: The disc valve design automatically compensates for wear under pressure, ensuring consistent high-torque output throughout the motor’s lifespan.

• Seamless System Integration: Designed specifically to drive externally supported shafts via an internal spline, reducing system friction losses.

• Precise OEM Interchangeability: Accurate matching with original specs like 151B0420 for guaranteed fit-and-function replacement in gearboxes.
