Poclain MS Series Radial Piston Wheel Drive Hydraulic Motors

Product Overview: The Poclain MS Series is the power nucleus for global mobile propulsion and heavy-duty industrial applications. As high-performance Low Speed High Torque (LSHT) radial piston motors, the MS series is renowned for its superior modularity and high power density. This page features the complete spectrum: from compact MS11 and MS18, mid-range MS25 and MS35, to heavy-duty MS50 and MS83, up to the high-capacity MS125-2-111-A83-3A50-0000. These motors are engineered for direct integration into wheel hubs, making them the premier choice for rotary drilling rigs, skid steer loaders, harvesters, heavy material handlers, and various construction machinery.

Key Technical Advantages:

• Heavy-Duty Bearing Support: Specifically designed for wheel drives, the internal oversized bearings support radial vehicle loads directly, eliminating the need for external gearboxes or supports.

• Elite Low-Speed Smoothness: Utilizing Poclain’s patented cam-ring technology, these motors ensure ultra-smooth operation even at speeds near 1 RPM, effectively eliminating “stick-slip” effects.

• Series 2 Iteration Technology: The MS125-2 represents a second-generation design with optimized fluid distribution, offering higher volumetric efficiency and extended service life under high-pressure conditions.

• Powerful Braking Integration: The modular housing easily integrates multi-disc wet brakes (e.g., A83 spec), providing absolute safety for incline parking and emergency braking.

• High Efficiency Performance: Rated for 400 Bar continuous operation with peak capabilities reaching 450 Bar. Mechanical efficiency exceeds 95%, significantly reducing system heat generation.

• Target Applications: Heavy excavator chassis travel, mining rig drives, forestry harvesters, port crane hoists, and agricultural tractor drive axles.
