DGR-MOB Series Hydraulic Cylinder  

Introduction 1. Cylinder Barrel Hydraulic equipment includes engineering hydraulic cylinder, hydraulic cylinder for metallurgical equipment, hydraulic cylinder for industry and thin hydraulic cylinder, etc. The commonly used materials of DGR-MOB Series Hydraulic Cylinder are seamless steel pipes of 20#, 35#, and 45#, which have been honed or rolled to meet the European roughness requirements of less than 0.4um. Low pressure oil cylinders can use 20# steel pipes, while high pressure oil cylinders can use 45# steel pipes. 2. Piston Rod There are two types of piston rods: solid rod and hollow rod. One end of the hollow piston rod should have a vent hole for welding and heat treatment. The material of the plug rod is 35# and 45# steel, and the material of the hollow piston rod is 35# and 45# seamless steel pipe. After rough machining, the piston rod is quenched and tempered to a hardness of 229-285HB. If necessary, it is then subjected to high…
