Poclain MS Motor | MS02, MS05, MS18, MS50, MS125, MS250 | High Torque Radial Piston Motor

Poclain MS Series High-Torque Radial Piston Drive Motors

Product Overview: The Poclain MS Series is the definitive global benchmark for mobile hydraulic propulsion. As a highly modular Low Speed High Torque (LSHT) radial piston motor, the MS series is specifically engineered to directly drive wheels, tracks, or various industrial winches. This featured selection covers the entire MS spectrum: from compact MS02, MS05, MS08, to mid-range MS11, MS18, MS25, MS35, and heavy-duty MS50, MS83, MS125, up to the massive MS250. Renowned for its superior efficiency and structural rigidity, the MS series is the primary choice for skid steer loaders, harvesters, rotary drilling rig chassis, marine winches, and heavy-duty wheeled chassis.

Key Technical Advantages:

• Elite Low-Speed Smoothness: Radial piston and cam-ring technology ensure constant torque output even at ultra-low RPMs, effectively eliminating “stick-slip” effects.

• Modular Integration: Motors can be customized with integrated service brakes, hydraulic parking brakes, dual-displacement valves (1C/2C), and specialized bearing supports.

• Direct Drive Architecture: Operates directly as a hub drive without the need for additional gearboxes, maximizing mechanical efficiency and minimizing chassis footprint.

• Extreme Shock Resilience: Built to withstand high-frequency vibrations, heavy shock loads, and massive radial/axial gravitational forces in harsh off-road terrains.

• Peak Pressure Capability: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, handling the most severe climbing and digging tasks.

• Target Applications: Crawler travel drives, agricultural propulsion axles, offshore winches, municipal sweepers, and TBM (Tunnel Boring Machines).
