MSE02-2-113-F03-2A50-K000 Poclain Hydraulic Motor 398cc LSHT

Product Overview

The MSE02-2-113-F03-2A50-K000 is a low-speed high-torque radial piston hydraulic motor built on the Poclain MS/MSE02 modular platform, featuring a dual-displacement configuration within the MSE02 series displacement module 2. The MSE02 series direct-drive motor delivers up to 22 kW (29.5 HP), with a displacement range of 172 to 398 cc/rev, a maximum working pressure of 400 bar (MSE version), a peak pressure of 450 bar, a maximum output torque of 2,500 N·m, and a maximum speed of 900 rpm, making it ideal for wheel motor or tool drive applications.

The model code MSE02-2-113-F03-2A50-K000 decodes as follows: MSE02 designates the series, 2 represents the displacement module size, 113 is the distribution shaft module code, F03 is the brake module code, and 2A50 is the output shaft configuration code. The MSE02 series motor employs a multi-piston radial layout with roller-type force transmission between the piston and cam ring, combined with a precision-machined distribution shaft module, ensuring stable torque delivery and excellent volumetric efficiency under low-speed heavy-load conditions.

Engineered as a form-fit-function replacement for original Poclain MSE02 series motors, this model maintains identical mounting flange dimensions, shaft specifications (2A50 standard output shaft), port configurations, and connection threads, enabling drop-in interchangeability without modification to the host machine’s mounting interface or hydraulic circuit. Core components are manufactured from imported materials and completed through precision machining centers, ensuring high accuracy and stable reliability.

Key Technical Advantages

1. Precision Radial Piston Pair with High Volumetric Efficiency

The MS/MSE02 series motor employs a multi-piston radial layout with roller-type force transmission between the piston and cam ring, effectively reducing contact stress and friction losses. Piston pair clearances are precision-controlled, combined with a precision-machined distribution shaft module, achieving volumetric efficiency above 90% at the rated pressure of 250 bar. Even at extremely low speeds, the motor maintains smooth operation without stick-slip or speed fluctuation. This design delivers high efficiency at any speed or operating pressure, contributing significantly to overall machine energy efficiency.

2. Modular Design with Flexible Configuration Capability

The MSE02 series adopts a standardized combination architecture of torque module, distribution shaft module, brake module, and output shaft module, with standardized interfaces between modules. In the model code, “113” designates the distribution shaft module, “F03” designates the brake module, and “2A50” designates the standard output shaft configuration. Optional modules include parking brakes, speed sensors, and flushing valves, with individual component replacement possible during maintenance or upgrade. The same torque module can adapt to either shaft motor or wheel motor mounting by changing the bearing support module, significantly reducing inventory costs and downtime.

3. High Power Density with Wide-Range Speed Control

The MSE02 series motor delivers up to 22 kW of power output within a compact structural envelope, with a maximum torque of 2,500 N·m, offering high power-to-weight ratio. Featuring a multispeed design, it achieves switching between full and half displacement through a dual-displacement mechanism, with a maximum speed of up to 900 rpm. Full-displacement mode delivers maximum torque for heavy-load starting and climbing conditions; switching to half displacement increases speed for no-load fast travel or light-load high-speed operation.

4. Extreme Condition Adaptability with Heavy-Load Bearing Capacity

The reinforced end cover and double-row roller bearing design enable the output shaft end to withstand extremely heavy loads. The bearing support module accommodates combined radial and axial loads, suitable for direct-load wheel drive applications. The motor housing is constructed from high-strength cast iron, with critical moving interfaces surface-hardened for long-term reliability in demanding mining, construction, and agricultural environments. An optional Twin-Lock™ anti-skid system provides additional traction control for wheel drive applications.

• Mining Equipment: Coal mine drills, heavy-duty handling vehicles, scraper conveyors, mini road headers

• Agricultural Machinery: Combine harvester travel drives, self-propelled sprayers, cotton pickers

• Material Handling: Forklift drives, aerial work platforms, aircraft tractors, beam carriers

• Municipal & Environmental Equipment: Road sweepers, refuse compactors

• Marine & Rail: Deck machinery, railway maintenance equipment

Expert Maintenance Tips

1. Shaft Alignment Requirements: Before installation, ensure the coaxiality deviation between the motor shaft and coupling does not exceed 0.05 mm to prevent premature bearing and shaft seal wear from excessive radial forces. The 2A50 output shaft configuration of the MSE02 series uses DIN 5480 standard splines; ensure the spline mating surfaces are free of burrs and damage during installation.

2. Initial Startup Preparation: Fill the motor housing with clean hydraulic fluid during initial installation to prevent dry friction on piston pairs during startup. The drain port (L port) must be connected separately to the reservoir with back pressure not exceeding 0.5 MPa; higher back pressure will damage the shaft seal and deform the housing.

3. Hydraulic Fluid Cleanliness: Maintain hydraulic fluid cleanliness at ISO 18/15 or NAS Level 9 or better. Replace hydraulic fluid and filter elements every 1,000 operating hours or annually, with filter element filtration accuracy no less than 10 μm.

4. Dual-Displacement Switching Mechanism Maintenance: Periodically verify the dual-displacement switching valve response pressure. Conduct switching tests every 500 operating hours using 3–5 MPa pilot pressure to ensure crisp, non-sticking actuation. If switching is sluggish, check pilot circuit pressure and valve spool wear.

5. Restart After Extended Storage: For motors stored over 6 months, manually rotate the shaft 2–3 revolutions to confirm free rotation, then run at low pressure (5 MPa) under no load for 10 minutes, confirming normal case temperature and leakage before gradually applying load.
