Poclain MS02 Radial Piston Motor | MS02-2-124-F02 | MS02-0-12A-F03

LIC Hydraulic specializes in the Poclain MS02 Series, a masterpiece of radial piston engineering designed for compact machinery requiring high torque and exceptional control. The MS02 family—featuring the MS02-2 double-speed and MS02-0 single-speed configurations—utilizes Poclain’s legendary cam-lobe technology to deliver maximum mechanical efficiency. Whether it’s the MS02-2-124-F02 for dynamic travel and work modes or the specialized MS02-0-12A-F03-YDGHJ for OEM applications, these motors provide surgical precision at ultra-low speeds and rugged durability under high-pressure cycles (up to $450\text{ bar}$).

Technical Highlights

• Radial Piston Cam-Lobe Design: Ensures constant torque output and high starting efficiency, ideal for climbing or heavy-load startups.

• Double-Speed Versatility: The -2 option allows for an on-the-fly displacement shift, optimizing machine performance for both speed and power.

• OEM Customization: Models with YDGHJ suffixes are built to specific manufacturer tolerances, ensuring a perfect drop-in fit for specialized industrial or mobile platforms.

• Integrated Multi-Disc Brake: High holding capacity within a zero-increase footprint, providing critical safety for slope operations.

Application Areas

• Compact Excavators: The definitive final drive for mini-diggers and track-mounted equipment.

• Agricultural Equipment: Driving systems for sprayers, seeders, and vineyard machinery.

• Specialized Handling: Powering heavy-duty AGVs (Automated Guided Vehicles) and compact winches.

Expert Maintenance Tips

• Case Priming: Never start an MS02 motor dry. Always fill the case with filtered oil through the drain port to ensure the piston rollers are lubricated before rotation.

• Case Drain Management: To preserve the high-pressure shaft seal, keep the case drain backpressure below $2\text{–}5\text{ bar}$. Use a dedicated return line directly to the reservoir.

• Fluid Condition: Maintain oil cleanliness at ISO 18/16/13. Particulate contamination is the leading cause of “scoring” on the cam-lobe track, which leads to efficiency loss and noise.
