Poclain MS18 & MSE18 Heavy-Duty Radial Piston Wheel Motors

Product Overview: The Poclain MS18 and MSE18 Series are high-performance Low Speed High Torque (LSHT) radial piston motors specifically engineered for medium-to-heavy mobile equipment. Featuring a modular design and extreme power density, these motors can be directly integrated into the wheel hub, eliminating the need for reduction gearboxes. This page highlights the high-precision model: MS18-2-121-A18-1330-00-MR. Its robust construction makes it the primary power choice for vibratory rollers, large excavators, construction drills, port cranes, and various all-terrain specialized vehicles.

Key Technical Advantages:

• Elite Load Capacity: Integrated with heavy-duty roller bearings, these motors are specifically designed to handle immense radial and axial loads (side loads) directly from the wheels.

• Compact MSE18 Optimization: The MSE18 series maintains the robust performance of the MS18 while shortening the axial length, facilitating installation in restricted chassis spaces.

• Integrated Braking Safety (1330): The 1330 code denotes an integrated multi-disc parking brake system, ensuring maximum stationary safety for machinery on extreme inclines.

• Smooth Efficiency: The radial piston architecture ensures smooth, creep-free torque delivery even at near-zero RPM.

• Enhanced MR Configuration: The MR suffix represents an optimized flow channel design, reducing internal heat generation and extending service life during high-load cycles.
