What Are The Materials For The Hydraulic Cylinder Piston Rod?

- Sep 07, 2019-

The material of the hydraulic cylinder piston rod is 45# steel, which is tempered and tempered. After surface turning and grinding, the chrome plating is 0.03~0.05mm thick.


1. The piston rod is a connecting part that supports the work of the piston. Most of them are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. Taking a hydraulic cylinder as an example, it consists of a cylinder, a piston rod (cylinder rod), a piston, and an end cover.


2. The quality of the piston rod processing directly affects the life and reliability of the entire product. The piston rod has high processing requirements, and its surface roughness requirement is Ra 0.4 to 0.8 um, which requires strict requirements on coaxiality and wear resistance.
