Poclain MS18 Series Dual-Displacement Radial Piston Wheel Motors

Product Overview: The Poclain MS18 Series is a premier power solution for medium-to-heavy-duty travel drives. As a definitive LSHT (Low Speed High Torque) radial piston motor, the MS18 is engineered for mobile machinery requiring massive traction and versatile speed control in grueling environments. This selection features two elite dual-displacement configurations: MS18-2-D24-F19-1220-5EJ0 and MS18-2-D21-A18-1230-DE00. Renowned for its exceptional radial load capacity, the MS18 series is the premier choice for rotary drilling rig travel, large combine harvesters, pavers, forestry equipment, and medium-sized crawler drive systems.

Key Technical Advantages:

• Dual-Displacement (2C) Versatility: The MS18-2 architecture enables dynamic displacement shifting, allowing machines to switch seamlessly between work mode (high torque) and travel mode (high speed) for maximum efficiency.

• Superior Radial Load Capacity: Utilizing F19/A18 reinforced bearing systems, it handles massive radial loads and lateral shocks directly from the wheels, eliminating the need for auxiliary support axles and simplifying chassis design.

• 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 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 complex operations.

• Integrated Functional Options: Available with optional multi-disc parking brakes and speed sensors to meet safety and feedback requirements.

• Target Applications: Rotary drilling rigs, agricultural propulsion, heavy-duty municipal sweepers, auxiliary winch systems, and construction wheel drives.
