ITMS series' hydraulic motor integrates the advantage of ITM and STF series'motor. It is a new concept hydraulic motors with higher comprehensive performance; Main characteristics: 1.Same structure as STF series as removed piston sleeve, integrated body case and piston cylinder hole; featured with high power-mass ratio and technical performance; 2.Applied hydrostatic oil-film modality between ball-socket of piston and ball head of con-rod to heighten its contact pressure ratio, working pressure and mechanical efficiency; 3.Special surface treatment of piston guarantees its permanent structure and low-friction seal that enables its higher volumetric and mechanical efficiency; 4.higher anti-impact and load performance due to its enhanced roller bearing; 5.Longer service life due to special materials and advanced heat treatment in main transmitting parts; 6.Same installation data as ITM series; an ideal replacement of ITM series in higher pressure & performance application.
