Poclain MS Series Heavy-Duty Radial Piston Wheel Motors

Product Overview: The Poclain MS Series stands as the global gold standard for hydrostatic transmissions in mobile machinery. Spanning a displacement spectrum from the versatile MS05/MS08 to the heavy-duty MS11/MS18, these LSHT (Low Speed High Torque) radial piston motors utilize legendary cam-lobe technology to deliver unparalleled smooth power at ultra-low speeds. This featured selection highlights high-performance configurations: MS11-0-D21-F11-1120-0000MR (Standard single-displacement) and MS18-2-D21-F18-1210-0000MR (Dual-displacement variable type). The MS series is the premier choice for rotary drilling rigs, pavers, forestry equipment, combine harvesters, and heavy material handling machines.

Key Technical Advantages:

• Superior Load Capacity: Optimized heavy-duty bearing systems specifically designed for wheel-end drives handle massive radial and axial loads directly, allowing the motor to act as a structural part of the machine chassis.

• Dual-Displacement (1C/2C): The MS18-2 model features dual-displacement capability, enabling seamless switching between working mode (high torque) and travel mode (high speed).

• Compact Modular Design: The radial piston architecture significantly reduces axial length, allowing for tight integration within wheel hubs or cramped mechanical compartments.

• Integrated Braking Solutions: Available with optional multi-disc parking or dynamic braking systems, ensuring safety for heavy equipment on slopes or complex terrain.

• Extreme Condition Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures up to 450 Bar, alongside exceptional thermal shock resistance.

• Target Applications: Road roller travel, skid steer loaders, municipal sweepers, shredder drives, and port machinery.
