Poclain MS11 Series High-Performance Radial Piston Wheel Motors

Product Overview: The Poclain MS11 Series is the global benchmark for heavy-duty drives in hydrostatic transmission systems. As a definitive LSHT (Low Speed High Torque) radial piston motor, the MS11 is engineered for mobile machinery requiring massive traction and precision control in grueling environments. This selection features three elite configurations: MS11-9-121-A11-1120, MS11-2-121-R11-1220-EJ00 (Dual-displacement), and MS11-8-124-F12-1720-58EJ (Specialized high-performance type). Renowned for its exceptional radial load capacity, the MS11 series is the premier choice for skid steer loaders, rotary drilling rigs, pavers, combine harvesters, and medium-sized crawler drive systems.

Key Technical Advantages:

• Dual-Displacement (2C) Versatility: The MS11-2 model enables dynamic displacement shifting, allowing machines to switch seamlessly between high-torque work mode and high-speed travel mode for maximum productivity.

• Heavy-Duty Wheel-End Bearings: Utilizing A11/R11/F12 reinforced bearing systems, it handles massive radial loads and lateral shocks directly from the wheels, ensuring reliability in grueling conditions.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, effectively managing instantaneous overloads and extreme stress cycles.

• Compact Modular Integration: The radial piston architecture minimizes axial length, allowing the motor to be integrated directly into wheel hubs or narrow crawler frames to optimize overall machine layout.

• Integrated Functional Options: Supports optional multi-disc parking brakes and speed sensors for enhanced system safety and precise operational control.

• Target Applications: Rotary drilling rig travel, agricultural propulsion, municipal sweepers, auxiliary winch systems, and construction wheel drives.
