The technology of the Hollow Hydraulic Cylinder Piston Rod in the process of processing will directly affect the quality of the piston rod and its service life. The processing of the piston rod is generally done by rolling, because this processing method can improve the corrosion resistance of the surface of the piston rod, delay the generation and expansion of fatigue cracks, and thus improve the fatigue strength of the piston rod. In addition, rolling can also reduce the surface roughness and reduce the occurrence of wear, so that the service life of the piston rod can be extended as a whole.
