The piston rod is a connecting part that supports the work of the piston. Most of them are used in the cylinder and cylinder motion actuators. It is a moving part with frequent movements 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 processing requirements of the piston rod are high, and the surface roughness requirement is Ra0.4～0.8μm, and the requirements for coaxiality and wear resistance are strict.
Piston rods are mainly used for hydraulic pneumatics, construction machinery, piston rods for automobile manufacturing, guide columns for plastic machinery, roller shafts for packaging machinery and printing machinery, shafts for textile machinery, conveying machinery, and linear optical axes for linear motion.
