Poclain MK47 MK35 MK09 Motor | MK47-2-A21-R18 | Two-Speed Variable Wheel Motor

Poclain MK Series Two-Speed Variable Radial Piston Wheel Motors

Product Overview: The Poclain MK Series is a premier solution for global mobile propulsion and industrial transmission. As an ultra-compact Low Speed High Torque (LSHT) radial piston motor, the MK series is specifically engineered to deliver massive power within a restricted axial footprint. This selection covers the entire spectrum: from compact MK04, MK05, MK08, and MK09, to the heavy-duty variable displacement MK35 and MK47. The featured model MK47-2-A21-R18-1140-7H00 offers dual-displacement shifting, allowing machinery to transition seamlessly between high-torque working modes and high-speed travel, making it ideal for rotary drilling rigs, heavy material handlers, mining machinery, and agricultural equipment.

Key Technical Advantages:

• Two-Speed Variable Functionality: Supports real-time dual-displacement (1C/2C) shifting, providing a perfect balance between high-torque capacity and high-speed mobility to maximize productivity.

• Ultra-Compact Architecture: The optimized fluid distribution design ensures a shorter axial profile than comparable motors, facilitating easy integration into wheel hubs or drilling heads.

• Elite Low-Speed Smoothness: Utilizing Poclain’s patented cam-ring technology, the motor delivers consistent, powerful torque at ultra-low RPMs, effectively eliminating “stick-slip” effects.

• Reinforced Bearing System: Built-in heavy-duty bearings handle massive radial loads directly, allowing the motor to drive wheel hubs or sprockets without additional support housings.

• High-Pressure Resilience: Rated for continuous operation at 400 Bar with peak capabilities reaching 450 Bar (6500 PSI), effortlessly handling frequent directional reversals and severe loads.

• Target Applications: Rotary drilling rig power heads, heavy skid steer loaders, port crane winches, harvester drive axles, and specialized mining vehicles.
