Abstract
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.

A swivelable journal bearing for a shaft, comprising:
- a shaft-supported inner ring with a spherically convex outer surface;
- an outer annular body divided into a multiplicity of socket elements rigidly welded to one another, said body coaxially surrounding said ring with clearance, each of said socket elements being provided with at least one throughgoing aperture facing said ring;
- a low-friction insert in each aperture projecting into said clearance, said insert having a spherically concave face in contact with and conforming to said outer surface;
- and
- a mass of concrete obstructing the end of each aperture remote from said ring in contact with the insert thereof for back-stopping same.
