Poclain MS Series Low Speed High Torque (LSHT) Piston Motors

Product Overview: The Poclain MS Series is a global benchmark in hydraulic transmission, renowned for its superior Low Speed High Torque (LSHT) performance. As a highly modular radial piston motor, the MS series is specifically engineered to meet the rigorous demands of direct-drive wheel propulsion or industrial machinery. This selection covers core frames: from compact MS02 and MS05 to mid-range MS08 and MS11, and high-torque MS18. It includes precision part codes such as MS11-2-D5E-M11-1920-58EFJM and MS-11-1-111-A11-2A50-E000. These motors are the premier choice for skid steer loaders, harvesters, rotary drilling rigs, marine winches, and municipal sweepers.

Key Technical Advantages:

• Elite Low-Speed Smoothness: The patented cam-ring design ensures ultra-smooth operation at exceptionally low RPMs, effectively eliminating “stick-slip” effects for precise maneuverability.

• Maximum Power Density: The compact radial layout delivers massive torque within a minimal footprint, ideal for recessed mounting within wheel hubs as a direct-drive unit.

• Highly Modular Configuration: Features diverse shaft options (splined, keyed), flanges (standard, plug-in), and integrated multi-disc wet brakes or speed sensor options.

• Exceptional Load Capacity: Built-in heavy-duty bearings directly support the radial and axial loads of the vehicle, significantly simplifying the chassis support architecture.

• High-Pressure Resilience: Rated for continuous operation at 400 Bar with peak capabilities reaching 450 Bar, handling frequent reversals and extreme overloads with ease.

• Target Applications: Crawler chassis drives, drilling rig rotation heads, forestry cutting drives, harvester travel, and winch propulsion.
