Stainless steel shaft is a connecting component that supports the piston to do work. It is mostly used in oil cylinders and cylinder motion execution components, and is a frequently moving and technically demanding moving component. Taking a hydraulic cylinder as an example, it consists of several parts: cylinder barrel, piston rod (cylinder rod), piston, and end cap. The quality of its processing directly affects the lifespan and reliability of the entire product.

The processing requirements for piston rods are high, with a surface roughness requirement of Ra0.4-0.8um, and strict requirements for coaxiality and wear resistance. The basic feature of oil cylinder rods is the processing of slender shafts, while piston rods are mainly used for hydraulic and pneumatic, engineering machinery, automotive manufacturing piston rods, plastic machinery guide columns, packaging machinery, printing machinery roller shafts, textile machinery, conveying machinery axis, and linear motion linear optical axis. After rolling, the reduction of surface roughness value can improve the fitting properties. At the same time, it reduces the friction damage to the sealing ring or seal during the movement of the cylinder rod piston, improves the overall service life of the cylinder, and the reasonable use of the piston rod can greatly improve the surface quality of the cylinder rod.
