Hydraulic cylinder is an important executive element in the hydraulic system of construction machinery, which is used to perform reciprocating motion and drive construction machinery to complete various functions.

The piston rod is a key force-transmitting part with high technical requirements for connecting the piston and the working parts in the hydraulic cylinder.

It needs to bear large tensile stress during the working process. Therefore, the piston rod must have sufficient strength, rigidity and toughness. Erosion by abrasive particles, it is easy to produce wear, and must have high wear resistance.
