Poclain MS Series High-Torque Radial Piston Hydraulic Motors (MS05-MS83)

Product Overview: The Poclain MS Series stands as the global benchmark for hydraulic travel drive technology. From the MS05 for compact equipment to the MS50 mid-heavy core, and the ultra-heavy MS83, these motors are renowned for their exceptional High Torque Low Speed (HTLS) performance. Thanks to a modular architecture, MS motors integrate directly into wheel hubs or shafts, providing massive startup traction without the need for gearboxes. This page highlights precision configurations: MS05-0-113-F04, MS50-2-G11-R50, and MS83-2-1B1-R83.

Key Technical Advantages:

• Comprehensive Displacement Range: From compact municipal machines to heavy mining loaders, the MS series covers a displacement range from 260cc up to 10,000cc for a perfect match.

• Dual-Displacement Capability: Models like MS50-2 and MS83-2 feature 2-Speed functionality, allowing seamless transitions between “High-Torque Work Mode” and “High-Speed Travel Mode.”

• Extreme Reliability: Robust cam rings and piston groups are engineered for extreme pressures of 400-450 Bar, capable of withstanding heavy radial loads and external shocks.

• Integrated Safety Features: Suffixes like 57EJ/Y7EJ denote integrated multi-disc parking brakes and enhanced seal kits, ensuring secure parking in harsh environments.

• Target Applications: Road roller travel drives, skid steer loaders, municipal sweepers, TBM propulsion, mining rigs, and heavy-duty winch systems.
