Poclain MS25, MS35, MS50 Heavy-Duty Radial Piston Hydraulic Motors

Product Overview: The Poclain MS Series stands as the global industry benchmark for high-power mobile propulsion. As high-performance Low Speed High Torque (LSHT) radial piston motors, the MS series handles extreme industrial and construction duty cycles through its robust modular architecture. This featured selection includes precision configurations: the heavy-duty powerhouse MS50-2-A11-A50-2A50-5J00, the classically reliable MS35-0-127-A18-7321-5800, and the precision-engineered MS25-2-D21-R25-1A10-E000. These motors are the premier choice for heavy excavator travel drives, rotary drilling rigs, large combine harvesters, forestry machines, and mining equipment.

Key Technical Advantages:

• Elite Power Density: The MS series delivers massive torque within a compact footprint, ideal for integration into wheel hubs or crawler drive boxes for large-scale machinery.

• Tiered Generation Technology (Series 0/2): * Series 2 (e.g., MS50-2/MS25-2): Second-generation design with upgraded distributor plates for superior volumetric efficiency and thermal stability at high pressures.

  • Series 0 (e.g., MS35-0): The classic Poclain workhorse, renowned for mechanical reliability and global serviceability.

• Massive Braking Integration: Modular housings integrate high-torque wet multi-disc parking brakes (e.g., A50, R25 specs), ensuring absolute safety for heavy-load incline holding.

• Superior Low-Speed Control: Patented cam-ring technology ensures constant torque output even at speeds near 0 RPM, effectively eliminating “stick-slip” effects for precise maneuverability.

• High-Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities reaching 450 Bar. Mechanical efficiency exceeds 95%.

• Target Applications: Crawler chassis propulsion, wheel drives, drilling head motors, port crane travel, and large-scale agricultural drive axles.
