Abstract
The invention relates to a rotary-anode X-ray tube which includes a sleeve bearing comprising an inner bearing member (9) and an outer bearing member (8). The inner bearing member itself includes three bearing portions, the first (94) of which takes up the axial bearing forces whereas the second bearing portion takes up the radial bearing forces and the third bearing portion (96) interconnects the first and the second bearing portion in such a manner that the symmetry axis (11) of the first or the second bearing portion can perform a swaying motion about the axis of rotation (10) during rotation of the two bearing members. Adequate bearing capacity is thus ensured even when the axial bearing surfaces do not extend exactly perpendicularly to the radial bearing surfaces.
