Product Overview

Model MS02-8-172-113-F03 is a compact multipurpose radial piston hydraulic motor manufactured under Poclain’s proven MS02/MSE02 series, with a rated displacement of 172cc tailored for light to medium-duty mobile machinery.Equipped with mature inner curve radial piston drive design, this hydraulic motor delivers stable low-speed high-torque output, and it can realize direct wheel hub drive without additional reduction gearboxes, which streamlines the whole transmission structure and reduces hydraulic energy loss effectively.It supports flexible modular optional components including integrated parking brake and rotational speed sensor, and boasts wide compatibility with both open-loop and closed-loop hydraulic circuits. The robust compact cast iron housing and precision-hardened internal piston and cam assemblies provide outstanding vibration-proof, dust-proof and wear-resistant performance, enabling reliable long-hour continuous operation on agricultural equipment, municipal sanitation vehicles and mini construction machines.

Key Features

• High-efficiency cam lobe radial piston hydraulic design Adopts mature Poclain cam piston principle, outputs stable high torque at low rotating speed to meet light and medium load drive needs of small construction and agricultural equipment.

• 172cc small-displacement mini compact structure Lightweight mini overall structure occupies less installation space, perfectly fits narrow frame mini machines such as small road rollers and mini loaders.

• Fully compatible OEM standard installation dimensions The flange, spline shaft and oil port sizes are completely consistent with the original MS02 series, supporting direct replacement without secondary mechanical processing to reduce machine downtime.

• Durable carburized alloy steel internal core components Cam rings and piston assemblies are forged and carburized, with balanced hardness and toughness, effectively resisting impact and dust abrasion for longer service life in outdoor construction and farm sites.

• Multi-layer composite sealing system for zero leakage performance Combined PTFE and nitrile rubber composite seals adapt to frequent hydraulic pressure and oil temperature changes, effectively avoiding internal and external oil leakage and maintaining stable volumetric efficiency.

• Integrated direct wheel hub installation to save transmission cost It can be directly installed on small wheel hubs without matching external reduction gearboxes, simplifying the whole hydraulic transmission chain and lowering comprehensive production and maintenance costs.

• Stable bidirectional reversible rotation without torque attenuation Precisely optimized internal flow distribution structure ensures smooth clockwise and counter-clockwise rotation without jitter or power drop, suitable for mini excavator walking systems, agricultural conveyors and light hydraulic winches.

• Reinforced thick alloy steel housing adapts to harsh outdoor environments Integrated thickened steel shell owns strong structural rigidity, which can block dust and muddy water splashes and resist mechanical vibration from construction yards and farmland.

• Full set of factory bench testing complies with international export standards Each finished hydraulic motor completes pressure endurance, efficiency and sealing tightness tests before delivery. Unqualified products are strictly screened to satisfy quality requirements of global machinery buyers.

• Wide universal matching range for multiple light compact machinery This MS02 series hydraulic motor has strong versatility, widely applicable to mini excavators, small road rollers, farm harvesters, garden machinery, compact transport vehicles and light hydraulic winch systems.
