Abstract: An X-ray emitter has a rotating anode rotatably mounted inside an X-ray tube by way of a multi-sliding surface bearing. The multi-sliding surface bearing has an inner and an outer sliding surface which are mounted so they can rotate relative to each other about an axis of rotation such that a gap is formed between the inner and outer sliding surfaces. A contour of the inner sliding surface, in a plane running perpendicular to the axis of rotation, is formed at least in certain sections by arc-shaped segments which are each centered around center points that are offset from each other.
