Seamless Steel Hydraulic Cylinder Honed Tube STKM13C, ST52, ST52.3, E355

Seamless Steel Honed Tube is made of JIS STKM13C/ DIN ST52/ ASTM A106/ SAE1020 and welded pipe: DIN ST52.3 are also offered. Seamless Steel Hydraulic Cylinder Honed Tube withstands higher pressure than welded tube without splits. But, roundness of welded honed barrels is superior to seamless pipe. After honing, carbon steel cylinder honed tube of mechanical structure use has precision diameter, smooth surface, and excellent performance of oil storage. This kind of Hydraulic Cylinder Tube and Pneumatic Cylinder Tube work smoothly without pauses and has longer working life in cylinders. Applies to hydraulic cylinders tube, pneumatic cylinders tube, forklift, crane, excavator, punching machine, and other kinds of labor-saving automatic mechanical engineering.
