What Is A Piston Rod

The piston rod is the connecting part that supports the work of the piston. Most of it is used in the oil cylinder and the cylinder motion execution part. It is a moving part with frequent movements and high technical requirements. Taking the hydraulic cylinder as an example, it is composed 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 is required to be Ra0.4 ~ 0.8μm, and the requirements for coaxiality and wear resistance are strict. The basic feature of the cylinder rod is the processing of the slender shaft, which is difficult to process and has always troubled the processing personnel.
