Abstract
Lubrication gas for a steel ball is delivered to the ball by a gas distribution manifold ring that surrounds an upper portion of the ball. Such ring presents an annular seat directed towards the ball and includes gas delivery orifices directed to discharge against the ball. Gas under pressure is delivered through the orifices, to provide a lubricating gas film between the seat and the ball, attended by downwardly directed fluid forces acting on the ball. A pressure chamber is provided below the ball. A regulated gas pressure is maintained within such chamber during pressurization of the bearing, for pressure loading the ball upwardly towards the bearing seat. A support pad ring is provided below the ball to support the ball during those times that the bearing is not pressurized and to preposition the ball to allow pressurization of the chamber below the ball by restricting the gap between the ball and the seat elements.
