Abstract: A hydrostatic journal bearing for a shaft of a heavy load, such as a metallurgical vessel, comprises an inner ring of spherical outer surface rigid with the shaft, a stationary base forming part of a housing, and a segmental shell resting on the base as a cradle for the ring. The upper shell surface has pockets for high-pressure oil, supporting the ring in operation, while the lower shell surface has similar pockets near its axially extending edges designed to maintain the shell curvature close to that of the ring. The shell may be split into two relatively axially shiftable coaxial subshells with further oil pockets at their interface.

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.

Abstract: The combination of an axially loaded rolling bearing with an hydrostatic thrust bearing in a tandem arrangement. The hydrostatic thrust bearing bears against a housing by means of a piston action, and externally produced hydrostatic fluid is conducted from a piston chamber over a controlled flow-off channel.
