Key Features of Hydraulic Piston Rods

The material of the hydraulic piston rod is 45 # steel, which has undergone quenching and tempering treatment, surface turning and grinding, and then chrome plating treatment, with a thickness of 0.03-0.05mm. The piston rod is a frequently moving and technically demanding moving component, mainly used in executive parts such as oil cylinders and cylinders. It supports the movement of the piston and directly affects the lifespan and reliability of the entire product. The machining requirements for piston rods are very high, with a surface roughness requirement of Ra0.4-0.8um, and strict requirements for coaxiality and wear resistance.
The working mode of the piston rod is reciprocating motion. In order to increase its service life and reduce wear, 38CrMoAlAn alloy structural steel is usually selected as the blank. According to the machining accuracy requirements of each part of the part drawing, the dimensional tolerance level of the forging is 8-12. The piston rod is generally produced in small batches and cylindrical blanks are selected.
The surface treatment of the piston rod is very important because its quality and performance directly affect the service life and reliability of the entire product. In hydraulic cylinders, the piston rod, cylinder barrel, piston, end cap, and other components work together to complete the movement of the cylinder. Therefore, selecting appropriate materials and processing techniques is crucial for improving the performance and lifespan of the entire hydraulic cylinder. In short, hydraulic cylinder piston rods are usually made of 45 # steel material, which undergoes quenching and tempering treatment, surface turning and grinding, and then chrome plating treatment. This material and processing technology can improve the life and reliability of the piston rod, ensuring the performance and service life of the entire oil cylinder.
