MS18-B-C21-F19-1220-58DJM Poclain Wheel Moto

Product Overview

The MS18-B-C21-F19-1220-58DJM, MSE18-2-G24-F19-1840-5FJD and related models (MS18, MSE18) belong to the Poclain Hydraulics MS/MSE series of high-pressure radial piston wheel motors (cam-lobe design). Designed for direct drive applications, these motors deliver high torque at low speeds, ideal for wheel motors. Fully interchangeable with original Poclain interfaces and performance (100% match), every unit undergoes 100% simulated operating condition testing. Ideal for mobile equipment, the series features precision radial piston technology, high starting torque, multi-speed options and optional brakes.

Key Technical Advantages

1. Precision cam and radial piston design delivers high starting torque and smooth low-speed operation with excellent volumetric efficiency.
2. Compact high-torque density: Direct-drive design reduces intermediate transmissions, saving space and weight.
3. Long-life bearings and high reliability: Supports high pressure and vibration for continuous operation.
4. 100% simulated duty testing and full interchangeability: Exact match to original Poclain interfaces and performance curves—true drop-in replacement with no modifications.
5. Flexible multi-speed and braking options: Supports dual displacement, anti-skid and multiple brake integrations.

Application Areas

Wheel drives in construction machinery, agricultural equipment, material handling, mining machinery, environmental machines, rail and marine auxiliary drives requiring high-torque low-speed direct drive.

Expert Maintenance Tips

Ensure the housing is correctly filled with oil through the drain port before start-up to prevent dry-running damage. Use hydraulic fluid meeting recommended viscosity and cleanliness levels. Periodically inspect seals, brake and bearings; perform moderate-load break-in initially. Strictly observe maximum pressure and speed limits. When replacing, verify the complete model code (including brake and flange options) for full interchangeability. Refer to official Poclain MS18-MSE18 technical manuals for precise torque-speed curves.
