グリングシール。 A radial oil guide hole is bored at the end of the center hole of the rotating shaft, and the rotating shaft is inserted into an annular groove facing the oil guide hole provided in the shaft hole of the casing through which the rotating shaft passes. In a cylindrical ring seal formed by inserting a cylindrical seal ring, a radial oil hole that communicates with the oil guide hole is bored on the center of the cylindrical seal ring, and a piston is installed at each end in the axial direction. A floating ring seal characterized in that a ring is fitted to provide an oil-tight seal between the outer periphery of the cylindrical seal ring and the bottom surface of the annular groove of the casing shaft hole.
