What material is used for the hydraulic cylinder barrel?
As the main component of the hydraulic cylinder, the processing quality of the hydraulic cylinder barrel directly affects the life and reliability of the entire product.
The cylinder has high processing requirements, and its inner surface roughness is required to be Ra0.4 ~ 0.8um, and the requirements for coaxiality and wear resistance are strict. Generally, it is processed and produced by the principle of honing or rolling.
The common materials of hydraulic cylinder barrel are SAE1020, 1035, 1045, ST52.3 seamless honed tube, the steel tube is honed or rolled to meet the roughness requirement within 0.4μm. The low-pressure oil cylinder can use 1020 steel pipe, and the high-pressure oil cylinder can use 1045 steel pipe.
