Poclain MK Series Motor | MK18-2-621, MK18-1-021, MK35-2-121 | LSHT Radial Piston Motor

Poclain MK Series Heavy-Duty LSHT Radial Piston Motors

Product Overview: The Poclain MK Series is the global gold standard for power and precision in hydraulic drives. As a definitive Radial Piston LSHT (Low Speed High Torque) motor, the MK series is specifically engineered for applications demanding massive torque at ultra-low speeds while withstanding extreme external radial loads. This selection highlights three core high-performance specs: MK18-2-621-F19-1340-0000, MK18-1-021-F12-1340-5800, and the heavy-duty MK35-2-121-A18-1140-7000. Utilizing Poclain’s legendary cam-lobe technology, these motors are the premier choice for rotary drilling heads, harvester wheel drives, heavy construction propulsion, and marine winches.

Key Technical Advantages:

• Ultimate Torque Delivery: The radial piston architecture ensures industry-leading mechanical efficiency during start-up and operation, delivering stable full-load torque even at 1 RPM.

• Extreme Radial Load Capacity: Reinforced housings and bearings designed for wheel-end mounting allow the motor to act as a direct structural axle, significantly simplifying machine chassis design.

• Multi-Displacement Control: Supports 2-speed (1C/2C) functionality, enabling a seamless transition between high-torque working mode and high-speed travel mode.

• Highly Integrated Features: Available with integrated multi-disc parking brakes and dynamic braking options, enhancing safety and compactness for mobile drive systems.

• Target Applications: Combine harvester propulsion, skid steer loaders, waste compactors, forestry harvesters, and TBM cutter head drives.
