Poclain MS MSE Series Hydraulic Motor | MS08 MS02 MS05 MS18 | Radial Piston Motor

The MS and MSE Series from LIC Hydraulic are premium Radial Piston Motors designed for the most demanding heavy-duty applications. Utilizing a multi-stroke design, these motors provide high-torque output directly to the drive wheel or shaft, eliminating the need for bulky gearboxes. Models like the MS08-2-G25-R08-1720-5DEJM are globally recognized for their modularity, allowing for integrated parking brakes and various displacement options. We provide 100% drop-in replacements that match original Poclain specifications for mounting dimensions, hydraulic porting, and dynamic load ratings.

Technical Highlights

• Range: MS02, MS05, MS08, MS11, MS18, MS25, MS35, MS50, MS83, MS125.

• Max Pressure: Continuous duty up to $400\text{ bar}$ ($5800\text{ psi}$), Peak up to $450\text{ bar}$.

• Max Torque: Up to $15,000\text{ Nm}$ (for MS08 frame) and beyond for larger sizes.

• Design: Radial piston, multi-stroke, modular interface.

Core Advantages

• Direct Drive Capability: The MS08 series is designed to function as a fully integrated wheel motor. Its robust housing and heavy-duty bearings support the full weight of the vehicle, reducing complexity and maintenance points.

• Unmatched Efficiency: High volumetric and mechanical efficiency ensure that maximum hydraulic energy is converted into drawbar pull, improving fuel economy and reducing heat generation.

• Dynamic Braking Options: Available with integrated multi-disc wet brakes (parking and emergency), providing superior safety and control in hilly or hazardous terrain.

• Shock Resistance: The radial piston design is inherently more resistant to pressure spikes and external mechanical shocks than axial piston alternatives, making it ideal for the harshest construction environments.

Expert Maintenance Tips

• Case Drain Management: Ensure the case drain line is connected to the highest port on the motor to prevent air pockets. Excess case pressure will damage the high-pressure shaft seal.

• Oil Cleanliness: To protect the precision-engineered cam ring and piston rollers, maintain hydraulic fluid cleanliness at ISO 18/16/13.

• Rotation & Bleeding: Before full-load operation, bleed the air from the motor by running it at low pressure. Entrapped air can cause cavitation damage to the cam surface during the piston return stroke.
