Abstract
A structure and associated method for forming a liquid metal or spiral groove bearing assembly for an x-ray tube is illustrated that utilizes a unitary sleeve and a thrust ring or seal each formed of a weldable, non-refractory material. The sleeve and the thrust seal are welded to one another to provide an improved construction for minimizing leaks of the liquid metal bearing fluid. The structure of the sleeve and the thrust seal are formed with deformation restricting features that maintain the integrity of the bearing surfaces of the assembly when the thrust seal is secured within the sleeve and welded thereto to form the bearing assembly.
