The surface of this cylinder piston rod is treated by special grinding and hard chrome plating technology, and then polished by mirror surface. so it also has a name as hard chrome bar.It has the characteristics of friction resistance and corrosion resistance, and is suitable for all kinds of air cylinders, oil cylinders, piston rods, packaging, textiles, printing and dyeing machinery, die casting machines, carpentry, injection molding and other machinery guide rods and ejector rods, etc. The material of piston rod can be divided into bearing steel, 45# steel, 40Cr ,42CrMo4 and stainless steel such as SS304 SS316, and the product grade can be divided into ordinary rod quenching rod. The surface of 45# steel piston rod is finished by special grinding and hard chrome plating technology, and then polished by mirror surface. It is wear-resistant and corrosion-resistant, and is suitable for all kinds of cylinders, oil cylinders, piston rods, packaging, carpentry, textiles, printing and dyeing machinery, die casting machines, injection molding machines, and guide rods and ejector rods for other machines.
