Product Overview

Poclain MS02-8-172-D4A-F03 belongs to the MS02 series small radial piston hydraulic motor with a 172cc displacement, specially developed for light and medium load wheel drive mobile machinery.Adopting mature cam curve radial piston driving structure, this hydraulic motor can produce stable large torque under low-speed running conditions. It can directly drive wheel hubs without being equipped with external reducers, which simplifies the overall layout of the whole machine and reduces the energy consumption of the hydraulic system.The motor supports multiple modular functional accessories such as built-in parking brake and speed measuring sensor, and can operate stably in both open and closed hydraulic circuits. The compact cast iron shell and wear-resistant precision internal core components have excellent vibration resistance, dust resistance and wear resistance, and can work continuously for a long time in farmland, urban roads and small construction sites.

Key Features

• Utilizing mature cam lobe radial piston hydraulic drive technology, it generates stable heavy torque at low rotational speed, perfectly satisfying the traction driving demand of mini construction and agricultural machinery.

• Equipped with 172cc displacement and miniaturized lightweight body, it effectively saves limited assembly space for narrow-frame compact equipment.

• Integrated hub direct mounting structure removes the need for external matching reduction boxes, streamlines the entire hydraulic transmission route and lowers comprehensive production and after-maintenance expenses.

• 100% OEM standard installation dimensions for flanges, splines and oil passages, supporting instant plug-and-play replacement without any secondary mechanical processing during equipment maintenance.

• Cam rings and piston moving assemblies are carburized forged alloy steel, balancing surface hardness and core toughness to withstand long-term impact and dust abrasion in harsh outdoor scenes.

• PTFE and nitrile rubber composite multi-layer sealing unit can adapt to variable hydraulic pressure and oil temperature, thoroughly avoid internal oil loss and external leakage.

• Thickened one-piece alloy steel housing has strong structural rigidity, which can effectively isolate dust, mud splashes and minor mechanical vibration on construction sites and farmlands.

• Precisely optimized internal flow channel structure ensures ultra-smooth bidirectional rotation, no rotation jitter, flow surge or torque drop during frequent forward and reverse switching.

• Wide working temperature window from -20℃ to +85℃, maintaining stable output performance in cold, high temperature, dusty and muddy harsh field working conditions.

• Every finished hydraulic motor passes strict bench tests of pressure durability, volumetric efficiency and sealing performance before shipment, fully meeting global export unified quality standards.
