摘要

Rotating anode X-ray tube has an axial bearing with a magnetic arrangement having two elements exerting a magnetic force fixed in an axial direction to the anode. The magnetic force receives axial bearing forces in one direction. Preferred Features: The first element is made of a magnetic ring (50) and the second element is a ring (55) made of a magnetizable metal. The bearing has a front surface with a ball lying in a cone. The ball has a coating made of TiC and/or TiN.
