Poclain MS25 Series High-Performance Radial Piston Wheel Motors

Product Overview: The Poclain MS25 Series is a versatile powerhouse in hydrostatic drive systems, perfectly balancing compact dimensions with heavy-duty performance. As a definitive LSHT (Low Speed High Torque) radial piston motor, the MS25 is engineered for off-road vehicles requiring massive traction and precision control. This selection features two core configurations: MS25-2-121-A25-1330-G0-MR (Dual-displacement) and MS25-0-111-R25-2A50-E000 (Standard single-displacement). Renowned for its exceptional radial load capacity, the MS25 series is the premier choice for combine harvesters, forklifts, compact rollers, rotary drilling rigs, and various wheeled mobile equipment.

Key Technical Advantages:

• Dual-Displacement Flexibility: The MS25-2 model features dynamic displacement shifting, allowing machines to switch seamlessly between high-torque (climbing/working) and high-speed (traveling) modes.

• Heavy-Duty Wheel-End Bearing: Utilizing the A25/R25 series reinforced bearing systems, it directly handles the vehicle’s radial weight loads, 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 consistent power in the toughest terrains.

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

• Integrated Braking Solutions: Available with optional integrated multi-disc parking brakes, providing maximum safety for heavy machinery on slopes.

• Target Applications: Agricultural propulsion systems, construction wheel drives, municipal sweepers, skid steer loaders, and industrial winches.
