Abstract:
A radial bearing for supporting a rotating shaft, which has a substantial elliptical-cylinder-shaped inner circumferential surface, a cross sectional shape of the inner circumferential surface perpendicular to the axial direction being an ellipse having two focal points, comprising,at least two protruding portions extending in the axial direction on the inner circumferential surface of the bearing, wherein the protruding portions are symmetric with respect to the central axis of the bearing to stabilize the shafting and comprise lubricating resin members provided on the inner circumferential surface of the bearing, wherein the protruding portions are located only in an area between the major axis of the ellipse, and 110 to 120 degrees therefrom in one circumferential direction on the inner circumferential surface; and an oil groove provided on an inner surface of the resin members in the vicinity of the major axis of the ellipse so as to extend in the axial direction of the bearing in a portion of the bearing between but not including both axial ends of the bearing.
