ABSTRACT:
The invention relates to a rotary anode X-ray tube with a sliding bearing, in particular a spiral flute bearing. In the case of such an X-ray tube, the passing of lubricant into the vacuum space of the X-ray tube, filled with a strong electric field in the operating state, is prevented by the surfaces, over which the lubricant reaches the space mentioned, being provided with a coating which can be wetted by the lubricant and forms an alloy with the latter.
