設けてなる油圧シリンダのロツドのシール装置。 It is provided on the rod cover part to seal between the rod of the hydraulic cylinder and the rod cover.
It is formed of a buffer device and a U-packet that are arranged in order from the pressure chamber side of the hydraulic cylinder, and the buffer device presses a buffer ring having a protrusion that comes into contact with the outer peripheral surface of the rod and the buffer ring from the outer periphery. In a hydraulic cylinder rod sealing device comprising an O-ring, a buffer ring, and an annular groove formed on the inner circumferential surface of a rod cover housing the O-ring, the pressure chamber is lower than the protrusion of the buffer ring. A sealing device for a rod of a hydraulic cylinder, comprising a communication portion that communicates a side of the buffer ring with an outer peripheral side of the buffer ring.
