テイングシール。 a housing; a shaft inserted into a circular hole formed in the housing and rotating relative to the housing; It is mounted on a roller bearing consisting of an outer ring that is bent toward an inward flange and a plurality of rollers provided between the inner circumferential surface of this outer ring and the outer circumferential surface of the shaft. It is a floating seal that controls the flow rate of lubricating oil flowing between the inner peripheral edge and the outer peripheral surface of the shaft, and has a U-shaped cross section, an annular shape as a whole, and an inner diameter slightly larger than the outer diameter of the shaft. , has an outer diameter smaller than the inner diameter of the outer ring and larger than the inner diameter of the inward flange, and with the opening side of the U-shaped cross section facing in the opposite direction to the roller, the roller and the inward flange are connected inside the outer ring. A floating seal for the roller bearing section that is installed between the roller bearing section and the roller bearing section.
