Poclain MK Motor | MK18-0-121 MK35-2-121 MK47-9-121 | Radial Piston Motor | LSHT Wheel Drive

Poclain MK Series High Power Density Radial Piston Motors

Product Overview: The Poclain MK Series consists of radial piston, low-speed high-torque (LSHT) motors specifically engineered for the most demanding operational environments. Compared to the standard MS range, the MK series features optimized internal geometry to deliver higher power density and extended service life within a compact envelope. This category features the heavy-duty models: MK18, MK35, and MK47. These motors are the premier choice for heavy self-propelled agricultural machinery, wheeled loaders, rotary drilling rigs, and underground mining vehicle drives.

Key Technical Advantages:

• Elite Torque Density: The MK series delivers massive tractive effort within a minimal footprint, making it ideal for direct installation within the hubs of heavy-duty machinery.

• Superior Load Resilience: Reinforced housings and high-capacity tapered roller bearings allow these motors to sustain massive radial and axial loads directly.

• Advanced Modularity:

  • Features the 121 sequence distribution logic for precise flow management.

  • Available with F12 and A18 standard flange interfaces for seamless integration with gearboxes.

• Extreme Pressure Ratings: Rated for a continuous pressure of 400 Bar with peak capabilities reaching 450 Bar (6500 PSI), ensuring reliability under frequent directional reversals.

• Target Applications: Grain harvesters, large vibratory rollers, road milling machines, and heavy-duty industrial mixing systems.
