Poclain MK04 & MK08 Compact LSHT Radial Piston Hydraulic Motors

Product Overview: The Poclain MK Series motors are specifically engineered for heavy-duty mobile and industrial drives where installation space is at a premium. As high-performance Low Speed High Torque (LSHT) radial piston motors, the MK series achieves extreme axial compactness through an optimized internal rotor design without compromising torque output. This page highlights two core configurations: the compact auxiliary drive MK04-2-114-K04-3310-3000 and the mainstream heavy-duty drive MK08-2-12A-F08-1340-A000. These motors are the premier choice for skid steer wheel drives, combine harvester propulsion, rotary drilling heads, and municipal sweepers.

Key Technical Advantages:

• Extreme Space Efficiency: The MK series is significantly shorter than the equivalent MS series, allowing for integration into narrower wheel hubs or tighter mechanical envelopes.

• Series 2 Optimization: The “-2-” designation represents the second-generation design, featuring higher back-pressure tolerance and upgraded volumetric efficiency for stable operation under high-temperature/high-pressure conditions.

• Integrated Heavy-Duty Braking: Modular housings seamlessly integrate multi-disc wet parking brakes (e.g., F08 specs) or specialized mounts (e.g., K04), ensuring absolute safety for incline holding.

• Elite Low-Speed Smoothness: Patented cam-ring technology ensures constant torque output even at speeds below 1 RPM, effectively eliminating “stick-slip” for millimeter-precision maneuverability.

• Heavy-Duty Bearing Support: Reinforced tapered roller bearings handle massive radial wheel loads and operational shocks directly.

• Target Applications: Wheel loader travel drives, mower deck drives, orchard harvesting machinery, and forestry attachment heads.
