Hydraulic cylinder component

The utility model relates to a hydraulic cylinder component comprising a cylinder barrel and a guide sleeve, a piston and a piston rod contained in the cylinder barrel, wherein the guide sleeve is fixedly held at one end of the cylinder barrel; a plurality of rubber seal rings are arranged between the contact surfaces of the guide sleeve and the cylinder barrel; a copper bush is further arranged on the inner surface of the guide sleeve; the piston moves along the extension direction of the cylinder barrel; one end of the piston rod is connected to the piston and pushes the piston to move; the piston rod passes through the guide sleeve; and the copper bush of the guide sleeve presses against the piston rod. For the hydraulic cylinder component, the copper bush with heavy intensity and good smooth finish is arranged on the inner surface of the guide sleeve so as to enable the guide sleeve and the piston rod to work for a long time and be hard to be worn, so that a whole hydraulic cylinder can be better in seali
