Piston Rod

The piston rod is a connecting part that supports the piston to do work. Most of it is used in the movement execution parts of the cylinder and cylinder. It is a moving part with frequent movement and high technical requirements. Taking the hydraulic cylinder as an example, it consists of: cylinder barrel, piston rod (cylinder rod), piston, and end cover. The quality of its processing directly affects the life and reliability of the entire product. The piston rod has high processing requirements, and its surface roughness requirements are Ra0.4~ 0.8μm, which has strict requirements on coaxiality and wear resistance. The basic feature of the cylinder rod is the processing of the slender shaft, which is difficult to process and has always plagued the processing personnel.
