Abstract
A spherical sliding bearing comprising a hollow inner rotating metallic shaft member having a spherical convex surface on its periphery, an outer load-carrying member having a spherical concave surface generally in conformity with the convex surface, the inner rotating shaft member being supported by the outer load-carrying member so as to freely rotate and oscillate under the sliding-contact relationship between the convex and concave surfaces, and a pressure-bearing seat being interposed between the convex and concave surfaces, which contains a fluorocarbon resin, a modifier dispersed in the fluorocarbon resin and a metallic member which is entirely embedded in the fluorocarbon resin and assures the strength of the pressure-bearing seat.
