MS08-2-111-R08-2A50-5BE0 Poclain Hydraulic Motor 934cc 450bar

Product Overview

The MS/MSE08 series is a core member of the Poclain Hydraulics MS multipurpose radial piston hydraulic motor family. Featuring a proven radial piston cam-ring design that is continuously improved, these motors represent the quintessential LSHT (Low-Speed High-Torque) direct-drive hydraulic motor category and have established themselves as an unrivaled benchmark in the hydraulic motor market worldwide.

The MS08 series is the Classic version, delivering maximum displacement of 1,248 cc/rev, maximum working pressure of 450 bar, maximum power of 41 kW, and maximum torque of 7,945 N.m. The MSE08 series is the HighFlow™ high-performance version, incorporating optimized port geometry and advanced valving design for higher speed and power output in the same compact package, with maximum working pressure of 400 bar. The MS/MSE08 series features a modular design with 1C (single displacement / single speed) and 2C (dual displacement / two-speed) configurations, with maximum speed reaching 450 rpm.

Our product provides a fully interchangeable direct replacement for the original Poclain Hydraulics MS/MSE08 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 MS08-2 offers 2:1 dual displacement switching (934 cc/rev ↔ 467 cc/rev). Low-speed mode (large displacement) delivers maximum torque output for heavy-load starting and climbing; high-speed mode (small displacement) provides higher output speeds (up to 170 rpm) for travel and transport. One motor covers two distinctly different operating conditions.

3. Ultra-High Pressure & High Reliability
The MS08 series delivers maximum working pressure of 450 bar and maximum torque of 7,945 N.m. The modular design enables easy deployment across construction equipment, material handling, agriculture, mining, rail, marine, and other demanding applications.

4. 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.

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 MS08-2-111-R08-2A50-5BE0 radial piston motor is widely used in travel drives and working function drives across construction and industrial equipment:

• Construction Equipment: Rollers, beam carriers, milling machines, backhoe loaders

• Road Construction Equipment: Roller vibratory drum drives

• Agricultural Machinery: Large sprayer travel drives

• Mining Equipment: Road headers, scrapers, heavy-duty handling cars, coal mine drills

• Specialty Vehicles: Fire engine travel drives

• Forestry Machinery: Stumpers, loaders, forest felling machines

• Material Handling: Belt conveyor drives

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—ensure the case drain line returns directly to the reservoir with the outlet below the oil level to prevent air entrapment and bearing starvation.

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

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

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

7. Weight is approx. 80 kg—use proper lifting equipment during installation and removal to prevent personal injury or component damage.

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

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