MSE18-1-127-R18-1110-57EH Poclain Hydraulic Motor 1911cc 400bar

Product Overview

The MSE series is the HighFlow™ high-performance version within the Poclain Hydraulics MS multipurpose radial piston hydraulic motor family. The MS series is Poclain Hydraulics’ globally renowned direct-drive hydraulic motor range, featuring a proven radial piston cam-ring design that has established itself as an unrivaled benchmark in the LSHT (Low-Speed High-Torque) hydraulic motor market worldwide.

The MSE series shares the same modular design platform as the MS series but incorporates performance-enhancing upgrades—including an integrated exchange valve and optimized port geometry—delivering higher speed and power output in the same compact package. MSE motors operate at 400 bar working pressure, compared to 450 bar for MS motors. The MSE series offers a complete displacement range from MSE02 to MSE50, covering 172 cc/rev to 15,000 cc/rev.

Our product provides a fully interchangeable direct replacement for the original Poclain Hydraulics MSE 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 an integrated exchange valve and optimized port geometry, delivering higher speed and power output in the same package. The MSE18 delivers maximum power up to 70 kW—leading among radial piston motors 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. 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 MSE18 series offers nine displacement code options from 1,091 cc to 2,812 cc.

5. Compact Design & High Power Density
Delivers 70 kW output power and up to 17,900 Nm maximum torque in a compact package. Direct-drive design eliminates intermediate transmission components, simplifying system architecture and improving overall efficiency.

Application Areas

The MSE18-1-127-R18-1110-57EH radial piston motor is widely used in travel drives and working function drives across construction and industrial equipment:

• Construction Equipment: Wheel loader and skid-steer loader travel drives

• Road Construction Equipment: Roller vibratory drum drives (Bomag, Dynapac, Hamm)

• Agricultural Machinery: Large combine harvester travel and header drives

• Mining Equipment: Underground mining vehicle and road header travel drives

• Material Handling: Telescopic handler travel drives

• Railway & Marine: Railway maintenance 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. Weight is approx. 117 kg — use proper lifting equipment during installation and removal to prevent personal injury or component damage.

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

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