Poclain MS & MSE Series High-Torque Radial Piston Hydraulic Motors

Product Overview: The Poclain MS and MSE Series represent the pinnacle of global hydraulic drive technology. Engineered as premier High Torque Low Speed (HTLS) power units, these motors are specifically designed for the wheel, shaft, and swing drives of heavy-duty machinery. Utilizing patented cam-lobe technology, they deliver massive startup torque at minimal RPMs without the need for complex gear reduction. This page offers a comprehensive range of drive solutions from the medium-sized MSE18 to the ultra-heavy MS83, serving as the ideal power heart for large excavators, mining trucks, crawler cranes, and heavy-duty winch systems.

Key Technical Advantages:

• Elite Torque Density: The radial piston architecture enables the motor to generate extreme torque within a compact envelope, driving heavy loads directly.

• Multi-Displacement Control: Most models feature 2-Speed or multi-displacement switching, allowing equipment to adjust speed and torque automatically based on the load.

• Superior Load Resilience: Equipped with reinforced bearings and shaft ends (e.g., F-series flanges or T-series splines), these motors directly support massive radial and axial loads.

• Integrated Braking & Valves: Supports integrated multi-disc parking brakes and makeup valves, significantly simplifying hydraulic routing while enhancing vehicle safety.

• Target Applications: Wheeled/tracked travel drives, TBM propulsion, forestry harvesters, mining crushers, and various heavy-duty hoisting systems.

Detailed Models & Displacement Specs:

• MSE18 Series: Compact heavy-duty motor, with displacements ranging from 1000cc to 2800cc.

• MS25 / MS35 Series: Medium-large drive cores optimized for high-frequency shock environments, supporting pressures up to 450 Bar.

• MS50 Series: Widely used in large construction machinery travel drives, delivering output torque exceeding 15,000 Nm.

• MS83 Series: Ultra-heavy flagship model, with displacements up to 5,000cc – 10,000cc, meeting extreme mining and tunnel boring requirements.

• Core Specs: Rated Operating Pressure 400 Bar (5800 PSI), Peak Pressure 450 Bar (6500 PSI).
