ABSTRACT:
The invention relates to a rotary-anode X-ray tube comprising a bearing arrangement for the rotary anode having at least two spiral groove bearings. A lubricant decoupling of the bearings adjoining each other is achieved in that the distance between the surfaces of the rotating part and the stationary part in the boundary region between the spiral groove bearings is enlarged.
