A swivelable journal bearing for a shaft of a converter or other heavy-duty equipment comprises a spherically convex inner ring on the shaft and an annular array of rigidly interconnected socket elements each forming at least one seat for an inwardly projecting low-friction insert having a spherically concave face in contact with the ring surface. The socket elements may be short tubes welded to one another or embedded in a shell of concrete; they could also be perforated strips welded together and backed by a concrete shell.
