A conical bearing apparatus is provided which is capable of enhancing productivity by reducing the time required for processing a hemispheric bearing i.e., grinding and lapping. By locating a spacer between a pair of cones, the cones are arranged on a fixing shaft facing each other and then inserted into a bush in which a pair of conical concaves for receiving the cones are formed. The thrust load and the radial load are supported by the dynamic pressure formed between the conical concaves and the dynamic pressure generating grooves formed on the tapered surfaces of the cones. Accordingly, as the bearing is conical shape, it is unnecessary to lap the hemispheric surface for minute clearance between the hemisphere and the hemispheric concave, thereby resulting in easy processing and enhancing the productivity of the bearing.
