The hollow double-piston cylinder manufacturer believes that when the piston rod is used in a hydraulic gas-liquid booster cylinder, its processing quality must be guaranteed. Generally, the processing requirements of piston rods are very high, requiring surface roughness of Ra 0.4 ~ 0.8 um, and strict coaxiality and wear resistance. Therefore, in order to meet the requirements of normal use, when making the piston rod, it is important to ensure that its length is appropriate. Generally speaking, its length value is controlled between 0.7 ~ 1.0 times the outer diameter (outer edge diameter) of the piston rod. This is mainly to enhance its guiding role, but also to expand the force-bearing area, reduce the degree of wear (a basic type of parts failure), and maximize the service life of the hydraulic gas-liquid booster cylinder. Hollow double-piston cylinder manufacturers believe that piston rods are mainly used in hydraulic and pneumatic, engineering machinery, automobile manufacturing piston rods, guide posts of plastic machinery, rollers of packaging machinery and printing machinery, shafts of textile machinery and conveying machinery, and linear motion.
