Beschreibung
Zusammenfassung:	The invention relates to the technical field of hydraulic cylinder pistons, in particular to a piston sealing device for a hydraulic cylinder. According to the technical scheme, the hydraulic cylinder comprises a hydraulic cylinder body, a hydraulic rod and a hydraulic piston, the hydraulic rod is movably installed in the hydraulic cylinder body, the hydraulic piston is installed at one end of the hydraulic rod in a sleeved mode, a piston oil seal ring is connected to the outer side of the hydraulic piston in a sleeved mode, and a wear-resisting ring is installed on the outer side of the hydraulic piston in a sleeved mode; and a first sealing ring is mounted on the inner side of the hydraulic piston and sleeves the outer side of the hydraulic rod. According to the hydraulic cylinder, the hydraulic piston, the piston oil seal ring and the wear-resistant ring are arranged, when the hydraulic rod conducts hydraulic piston movement, the hydraulic piston moves in the hydraulic cylinder body, the piston oil seal ri
