MSE02-0-123-F03-1120-5J00 Poclain Hydraulic Motor 398cc 400bar

Model 1: MSE02-0-123-F03-1120-5J00

Product Overview

The MSE02-0-123-F03-1120-5J00 is a single displacement (single speed) model in the Poclain Hydraulics MSE02 series HighFlow™ high-performance radial piston hydraulic motor family. The MSE series represents the HighFlow™ performance upgrade of Poclain’s renowned MS multipurpose radial piston motor range, featuring a proven radial piston cam-ring design that defines the LSHT (Low-Speed High-Torque) direct-drive hydraulic motor category.

The MSE02 series delivers maximum displacement of 398 cc/rev, maximum power of 22 kW, and maximum pressure of 400 bar (max torque 2,500 N.m), with high speed reaching 900 rpm through multispeed design. The MSE series shares the same modular design platform as the MS series but incorporates optimized port geometry and advanced valving design for higher speed and power output in the same compact package. The “-0” suffix in MSE02-0 denotes 1C (single displacement / single speed) configuration, offering a simple and reliable solution for constant-torque applications where cost-effectiveness and robustness are priorities.

Our product provides a fully interchangeable direct replacement for the original Poclain Hydraulics MSE02 series motor, with identical mounting dimensions, port specifications, and shaft configurations. Every unit undergoes 100% simulated duty-cycle testing—performance-validated under rated pressure, peak pressure, and full speed range to ensure volumetric efficiency, mechanical efficiency, torque output, noise levels, and thermal characteristics meet or exceed original OEM specifications.

Key Technical Advantages

1. Radial Piston Cam-Ring Design — Industry Benchmark
The MSE series features the proven and continuously improved radial piston cam-ring technology. Working cylinders are radially arranged around a crankshaft, with pistons actuated by the cam ring. This design delivers exceptional efficiency at any speed or operating pressure, combined with outstanding impact resistance and heavy-load capacity.

2. HighFlow™ Performance Optimization
As the HighFlow™ version of the MS series, the MSE incorporates optimized port geometry and advanced valving design, delivering higher speed and power output in the same package. The MSE02 delivers maximum power up to 22 kW and maximum torque of 2,500 N.m—among the best in its class.

3. Ultra-High Starting Torque & Superior Low-Speed Stability
The radial piston cam-ring design endows the MSE series with exceptionally high starting torque — approaching 90% of theoretical torque. The motor operates smoothly at extremely low speeds, enabling direct load drive without additional speed reducers.

4. Compact Design & High Power Density
Delivers 22 kW output power and 2,500 N.m maximum torque in a compact package. Direct-drive design eliminates intermediate transmission components, simplifying system architecture and improving overall efficiency.

5. Modular Design & Versatile Configurations
The MSE series features a modular design philosophy, offering both wheel motor and shaft output configurations. Optional service brake, parking brake, and Twin-Lock™ integrated anti-skid functionality are available. The modular design enables easy deployment across construction equipment, material handling, agriculture, mining, rail, marine, and industry.

Application Areas

The MSE02-0-123-F03-1120-5J00 radial piston motor is widely used in travel drives and tool drives across construction and industrial equipment:

• Construction Equipment: Skid-steer loader and mini-excavator travel drives

• Material Handling: Forklift and telescopic handler travel drives

• Agricultural Machinery: Large sprayer travel drives, combine harvester header drives

• Mining Equipment: Underground mining vehicle travel drives

• Railway Maintenance: Track maintenance equipment travel drives

• Marine Machinery: Marine deck cranes

• Industrial Drives: Winch drives and heavy material handling equipment

Expert Maintenance Tips

1. Shaft seals and all O-rings must be replaced after every disassembly.

2. Pre-lubricate all moving parts with clean hydraulic fluid before assembly.

3. Purge all air from the motor housing before initial start-up, and run at moderate load and speed for 10–15 minutes for break-in.

4. Recommended maximum system operating temperature should not exceed 82°C to ensure seal and fluid service life.

5. Monitor case drain flow regularly — an abnormal increase indicates potential piston or cylinder wear.

6. Ensure hydraulic system filtration meets β₁₀ ≥ 75 (ISO 4406 cleanliness code不低于 18/16/13) to maximize motor service life.

7. For wheel mount applications, strictly follow specified bolt torque and use thread-locking compound to prevent loosening.

Model 2: MSE02-1-1LA-F03-2AC5-Y3FJM

Product Overview

The MSE02-1-1LA-F03-2AC5-Y3FJM is a two-speed (dual displacement) model in the Poclain Hydraulics MSE02 series HighFlow™ high-performance radial piston hydraulic motor family. The MSE02 series delivers maximum displacement of 398 cc/rev, maximum power of 22 kW, and maximum pressure of 400 bar (max torque 2,500 N.m), with high speed reaching 900 rpm through multispeed design. The “-1” suffix in MSE02-1 denotes 2C (dual displacement / two-speed) configuration, accommodating both low-speed high-torque and high-speed light-load operating conditions via displacement switching.

The MSE series shares the same modular design platform as the MS series but incorporates optimized port geometry and advanced valving design for higher speed and power output in the same compact package. Our product provides a fully interchangeable direct replacement for the original Poclain Hydraulics MSE02 series motor, with identical mounting dimensions, port specifications, and shaft configurations.

Key Technical Advantages

1. Two-Speed Dual Displacement — Two Motors in One
The MSE02-1 offers 2:1 dual displacement switching (398 cc/rev ↔ 199 cc/rev). Low-speed mode (large displacement) delivers maximum torque output (2,500 N.m) for heavy-load starting and climbing; high-speed mode (small displacement) provides higher output speeds (340 rpm at half displacement) for travel and transport. One motor covers two distinctly different operating conditions.

2. HighFlow™ Performance Optimization
As the HighFlow™ version of the MS series, the MSE incorporates optimized port geometry and advanced valving design, delivering higher speed and power output in the same package. The MSE02 delivers maximum power up to 22 kW and maximum torque of 2,500 N.m.
