Poclain MS Series High-Torque Radial Piston Hydraulic Motors

Product Overview: The Poclain MS Series represents the global benchmark for hydraulic transmission, specifically engineered for the most demanding travel drive conditions. As a premier High Torque Low Speed (HTLS) motor, the MS series delivers massive startup traction directly at the wheel hub or shaft without the need for mechanical gearboxes. This page features precision configurations: MS18-2-D2A, MS50-2-D21, and MS08-0-125. These motors are the vital power heart for large road roller travel, skid steer loader drives, heavy-duty municipal sweepers, TBM propulsion, and specialized work machinery.

Key Technical Advantages:

• Elite Torque Density: The modular radial piston architecture ensures maximum torque from a standstill, meeting the rigorous demands of heavy-load starts and incline navigation.

• Dual-Displacement (2-Speed) & Single-Displacement Options:

  • MS18-2/MS50-2: Feature displacement switching functionality, allowing machinery to balance “Work Mode” (high torque) with “Travel Mode” (high speed) seamlessly.

  • MS08-0: Classic fixed displacement delivering constant and reliable high-efficiency power output.

• Reinforced Interface Adaptation: Interfaces like R18, F83, and R50 utilize ultra-heavy-duty bearing designs to directly support extreme axial and radial loads.

• Integrated Safety & Logic: Suffixes like 5DM0, 7E00, and 7P00 denote integrated multi-disc parking brakes and customized control logic (e.g., A40620C sequence), enhancing both system safety and compactness.

• Target Applications: Wheel excavator travel, large vibratory rollers, municipal sweepers, agricultural drives, and heavy-duty industrial winch systems.
