Poclain MS11 Series High-Performance Radial Piston Wheel Motors

Product Overview: The Poclain MS11 Series is a globally recognized cornerstone for medium-to-heavy-duty drives. As a definitive LSHT (Low Speed High Torque) radial piston motor, the MS11 is engineered for mobile machinery requiring massive traction within a compact installation envelope. This selection features two elite configurations: 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, forestry equipment, 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 working mode (high torque) and travel mode (high speed) for maximum productivity.

• Heavy-Duty Wheel-End Bearings: Utilizing 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.

• 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 machine layout.

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

• Target Applications: Road roller drum drives, agricultural propulsion, municipal sweepers, and auxiliary winch systems.
