stf radial piston motors

STF – ITMH – Radial Piston Motor ITMH series-01,02,03,06,08,11,16. Max. Pressure upto 210 bar. Max Torque upto 180 to 6434. ITHM high pressure high speed hydraulic motor is an upgrade of the ITM series, its internal integrated with multiple valve group, the critical friction pair is redesigned, these improved the comprehensive performance and reliability of the motor remarkably.

STF – ITM Series – Radial Piston Motors ITM series-01,02,03,06,08,11,16,31,70,100. Max. Pressure up to 220 bar Rated Torque range 150 to 19843 N.m Main Characteristics: Low noise due to its crankshaft &con-rod structure and cylinder & piston framework of low vibration frequency. Steady performance at low speed; high starting torque. Good reliability and less leakage due to the flat compensation distributor. Enable reversible rotation and certain external radial & axial force on output shaft.

STF – ITMS Series – Radial Piston Motors ITMS series-09,18,30 Max. Pressure up to 220 bar Rated Torque range 1983 to 8930 N.m Main Characteristics: 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. 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. Higher anti-impact and load performance due to its enhanced roller bearing. Longer service life due to special materials and advanced heat treatment in main transmitting parts. Same installation data as ITM series, and ideal replacement of ITM series in higher pressure & performance application.

STF – STFC Series – Radial Piston Motors STFC series-080,100,125,200,270,325,400 Max. Pressure up to 290 bar Rated Torque range 3324 to 22404 N.m Main Chratcteristics: The hydrostatic balance built between the piston, con-rod and eccentric sets reduces the friction between con rod and eccentric sets, and also reduce the lateral friction on pistons, and contact pressure on ball the socket, thus to reduce the friction loss while on load. With above STFC series motor features with high mechanical efficiency and starting torque (The Mechanical efficiency while starring is upto 90%) Hydrostatic balance shaft distributor prevent the shaft from tilting. thus to get excellent sealing, less leakage, and continuous running under high pressure (Max. pressure reach to 29Mpa) Special materials and structure of seals reduce the leakage and improve the volumetric efficiency. Special materials and advanced treatment on main driving parts prolong the overall service life. Ideal replacement of STAFFA motor with interchangeable mounting and performance. STFC series motor is widely applied in all kinds of hydraulic transmission systems. such as plastic injection molding machines, deck machinery, construction machinery, hoist, transport vehicle, heavy metallurgical machinery, petroleum & mining machinery, light industrial equipment, drilling machinery and so on.
