Poclain MS Series High-Torque Radial Piston Hydraulic Motors

Product Overview: The Poclain MS Series radial piston motor is the industry benchmark for hydrostatic drives, renowned for its extreme torque density and modular configuration. These motors are designed to drive wheels directly or connect to industrial loads via flanges. This selection features core specifications: from the compact MS05 to the heavy-duty MS50, including specific models MS50-2-D21-F83-1330-7P00, MS05-1-113-A05-2A50-7M00, and MS50-2-A21-R50-2A50-7E00. Utilizing its unique cam-ring design, the MS series maintains superior smoothness and extended service life even at peak pressures up to 450 Bar.

Key Technical Advantages:

• Outstanding Low-Speed Torque: The radial piston architecture ensures 100% of nominal torque is available from zero speed, effectively eliminating “stick-slip” in heavy machinery.

• High Load Capacity: Features integrated heavy-duty bearings capable of handling significant radial and axial forces, eliminating the need for external support structures.

• Modular Function Integration: Supports integrated multi-disc wet brakes (parking brakes), 2-speed displacement shifting, and various valve blocks to save installation space.

• High-Pressure & Shock Resilience: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6525 PSI) peak pressure, handling frequent shock loads in mining and construction.

• Target Applications: Skid steer loaders, forestry machinery, rotary drilling rigs, mining crawler drives, marine winches, and municipal sweepers.
