Poclain MS11 Motor | MS11-0-121-R11, MS11-1-121-A11 | Radial Piston Wheel Motor

Poclain MS11 Series High-Performance Radial Piston Wheel Motors

Product Overview: The Poclain MS11 Series is a 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 two core configurations: MS11-0-121-R11-1920-EJ00 and MS11-1-121-A11-1320-0000. 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:

• Superior Radial Load Capacity: Utilizing R11/A11 reinforced bearing systems, it handles massive radial loads and lateral shocks directly from the wheels, eliminating the need for auxiliary support axles.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, ensuring long-term stability under extreme load cycles.

• Compact Modular Integration: The radial piston architecture minimizes axial length, allowing the motor to be integrated directly into standard wheel hubs to optimize overall machine width.

• High Mechanical Efficiency: Optimized cam-lobe technology ensures smooth, massive torque output even at ultra-low speeds, providing precise control for climbing and operation.

• Integrated Functional Options: Available with optional multi-disc parking brakes and speed sensors to meet the feedback requirements of complex hydraulic systems.

• Target Applications: Road roller drum drives, agricultural propulsion, municipal sweepers, auxiliary drive systems, and heavy-duty industrial winches.
