Poclain MSE02 & MSE05 Hydraulic Motor | MSE02-2-123-A02-1240-K000 | Radial Piston Drive

LIC Hydraulic presents the Poclain MSE02 and MSE05 Series, the industry-standard for high-performance radial piston hydraulic motors. Engineered for Low-Speed High-Torque (LSHT) applications, these motors (such as MSE02-2-123-A02-1240-K000) offer exceptional power density and reliability. The multi-cam lobe design ensures smooth rotation even at ultra-low speeds, making them perfect for direct wheel drives. We provide 100% drop-in replacements for MSE series motors, ensuring your machinery operates with original factory precision and durability.

Technical Specifications Highlights

• Displacement Range:

  • MSE02: $172\text{–}332\text{ cm}^3\text{/rev}$

  • MSE05: $376\text{–}750\text{ cm}^3\text{/rev}$

• Max Pressure: Up to 450 bar (Intermittent)

• Max Torque: High startup torque efficiency ($\approx 95\%$)

• Configuration: Wheel motor (with brake) or Shaft motor options.

• Key Features: Integrated multi-disc brakes, heavy-duty bearings, and optional speed sensors.

Key Technical Advantages

• Direct Drive Capability: The heavy-duty bearing carrier is designed to support high radial loads, allowing the vehicle’s wheels or sprockets to be mounted directly to the motor.

• Superior Smoothness: The radial piston configuration provides constant torque output throughout the rotation, eliminating the “pulsing” effect often found in smaller motors at low speeds.

• Modular Versatility: Customize your drive with integrated valving, multiple brake sizes, and various displacement options within the same frame size.

• Robustness: Radial piston technology is inherently more resistant to hydraulic shocks and particle contamination than axial piston designs, leading to a longer service life in harsh environments.

Application Areas

• Construction: Skid steer loaders, mini-excavators, and trenchers.

• Roadwork: Drive systems for rollers, asphalt pavers, and milling machines.

• Agriculture: Self-propelled sprayers, grape harvesters, and forestry equipment.

• Industrial: Heavy-duty conveyor drives and winch systems.

Expert Maintenance Tips

• Case Drain Integrity: Always ensure the case drain line is connected to the highest port and returns directly to the tank. Excessive case pressure will cause shaft seal failure and internal damage.

• Fluid Cleanliness: Maintain oil at ISO 18/16/13 or better. While robust, the precision cams and rollers require clean lubrication to prevent surface pitting.

• Brake Release Pressure: For motors equipped with integral brakes, verify that the release pressure meets the OEM spec. Operating with a partially engaged brake will cause catastrophic overheating.
