Product Overview

The Poclain MS02-MSE02 is a large-displacement radial piston hydraulic motor covering 172–398 cc/rev, delivering up to 2,500 Nm torque at 450 bar (MS) / 400 bar (MSE) rated pressure, 22 kW power, and 900 RPM maximum speed. Its multi-lobe cam ring radial piston architecture uses pure rolling contact between pistons and cam surface, yielding high mechanical efficiency, strong starting torque, smooth low-speed operation without stick-slip, and minimal internal leakage even under sustained stall conditions at full pressure. Dual-displacement switching enables low-speed high-torque working mode (crushing, conveying, mixing) and high-speed travel mode from a single motor without an external gearbox. The modular platform supports standalone shaft output and integrated wheel motor configurations, with optional parking brake, service brake, and TwinLock anti-skid functionality. Free-wheeling mode simplifies equipment towing and emergency extraction. The cast steel housing with high-pressure multi-lip shaft seals withstands underground dust, surface mud and water, shock loading, and 24/7 continuous operation. Typical mining applications include roof bolters, shuttle cars, and tracked carriers, alongside stationary industrial drives such as crushers, screw conveyors, and rotary kilns — replacing complex gearbox-plus-motor drivetrains with a single direct-drive unit that eliminates intermediate transmission stages and reduces daily maintenance touchpoints.

Key Features

• Compact Radial Piston Structure Adopts mature radial piston design, small overall volume and lightweight body, easy to install on narrow space engineering and agricultural equipment.

• High Starting Torque & Stable Low-Speed Performance Large torque output at low rotation speed, no crawling phenomenon, stable power supply under heavy-load low-speed working conditions.

• Wide Displacement & Strong Adaptability Complete displacement options for MS02-MSE02 series, supports single-speed and two-speed versions to meet diversified drive demands.

• High Efficiency & Low Energy Consumption Optimized piston-cylinder friction pair and flow distribution structure reduce internal leakage and power loss, lower system heat generation.

• Heavy-Duty Wear-Resistant Internal Components Pistons, cam rings and valve plates made of high-strength alloy steel via precision grinding, excellent abrasion resistance for long continuous operation.

• Reliable Multi-Layer Sealing Assembly Imported high-temperature, oil-resistant and anti-aging sealing components, effectively prevent internal pressure loss and external oil seepage.

• Strong Shock & Vibration Resistance Integrated high-rigidity cast housing, can withstand frequent impact and long-term vibration in construction, road and farm working sites.

• Integrated Brake Optional Configuration Supports built-in mechanical parking brake structure, stable braking performance, improves equipment safety during shutdown and slope stay.

• Universal Standard Mounting Interface Unified flange, shaft and oil port specifications, good interchangeability to replace original Poclain MS02/MSE02 without structural modification.

• Broad Multipurpose Application Coverage Widely used for road rollers, sweepers, small loaders, harvesters, aerial work platforms and other light to medium heavy-duty mobile machinery.
