MS05-2-133-R05-122R-EFJM Poclain Hydraulic Motor 750cc 450bar

Product Overview

The MS series is Poclain Hydraulics’ globally renowned multipurpose direct-drive hydraulic motor range, featuring a proven radial piston cam-ring design that represents the quintessential LSHT (Low-Speed High-Torque) motor category. With exceptional low-speed stability, ultra-high starting torque, and outstanding reliability, these motors have established themselves as an unrivaled benchmark in the hydraulic motor market worldwide.

The MS series offers a complete displacement range from 172 cc/rev to 15,000 cc/rev, with maximum working pressure up to 450 bar and high speed up to 700 rpm achieved through multispeed design. The MSE series—as the HighFlow™ performance version of the MS series—incorporates optimized design features to deliver higher speed and power output in the same compact package.

Our product provides a fully interchangeable direct replacement for the original Poclain Hydraulics MS/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 MS 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. Two-Speed Dual Displacement — Two Motors in One
The MS05-2 offers 2:1 dual displacement switching (750 cc/rev ↔ 375 cc/rev). Low-speed mode (large displacement) delivers maximum torque output (1,193 Nm/100 bar) for heavy-load starting and climbing; high-speed mode (small displacement) provides higher output speeds (up to 265 rpm) for travel and transport.

3. Ultra-High Starting Torque & Superior Low-Speed Stability
The radial piston cam-ring design endows the MS 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 29 kW output power and 1,193 Nm/100 bar torque in a compact package. Direct-drive design eliminates intermediate transmission components.

5. Modular Design & Versatile Configurations
The MS 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.

Application Areas

The MS05-2-133-R05-122R-EFJM radial piston motor is widely used in travel drives and working function drives across construction and industrial equipment:

• Road Construction Equipment: Roller vibratory drum drives (Amkodor 2551, Amkodor 2561)

• Construction Equipment: Skid-steer loader travel drives

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

• Material Handling: Telescopic handler travel drives

• 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. Two-speed shifting should be performed under low-load or zero-load conditions to prevent impact damage to the displacement switching mechanism.

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.
