Poclain MS25 Series High-Torque Radial Piston Hydraulic Motors

Product Overview: The Poclain MS25 Series is a world-class radial piston hydraulic drive engineered for heavy-duty mobile machinery. As a premier High Torque Low Speed (HTLS) motor, the MS25 delivers massive startup torque at minimal RPMs without the need for additional mechanical gear reduction. This page features core configurations: MS25-0-121-P35 and MS25-0-121-A25. These motors serve as the vital power heart for wheel loaders, heavy-duty road rollers, specialized mining vehicles, skid steer travel drives, and industrial mixing systems.

Key Technical Advantages:

• Superior Power Density: The compact radial piston architecture allows for extreme torque output within a limited footprint, significantly optimizing chassis layout.

• Robust Load Bearing: Interfaces like P35 and A25 utilize reinforced bearing supports to directly withstand heavy radial and axial loads at the wheel hub or shaft end.

• High Startup Efficiency: Optimized cam-lobe technology ensures maximum torque is available from a standstill, making it ideal for heavy-load starts and incline climbing.

• Integrated Safety Braking: Suffixes like 5FG0 denote integrated multi-disc parking brakes, providing secure and reliable braking functionality within the compact wheel-end envelope.

• Target Applications: Large sweeper travel drives, harvester wheel drives, TBM auxiliary power, heavy-duty industrial winches, and mining drill heads.
