The utility model relates to a noise reduction hydraulic piston assembly. The noise reduction hydraulic piston assembly comprises a cylindrical piston body. A piston rod is installed at one end of the piston body, multiple ring grooves are formed in the cylindrical outer surface of the piston body, a groove is formed in the middle, at the end away from the piston rod, of the piston body, a sound elimination pad is installed at the end of the groove, springs are installed in the groove, one end of each spring is connected to the inner wall of the groove, and the other end of each spring is connected to the sound elimination pad. The noise reduction hydraulic piston assembly is simple in structure and reasonable in design, the groove is formed in the piston body, the sound elimination pad is installed at the end of the groove, and therefore noise generated in the operating process of a piston can be lowered.
