ABSTRACT:
An X-ray tube has a rotating anode and a plain bearing for mounting the rotating anode in a vacuum housing. The plain bearing has an inner bearing part that is stationary in relation to the vacuum housing, and a rotating outer bearing part that is connected with the rotating anode and that rotates with this anode relative to the vacuum housing during the operation of the X-ray tube. Between these inner and outer bearing parts there is a bearing gap filled with lubricant at least in the region provided for the transmission of force. The inner bearing part, which extends through the outer bearing part, is connected to the vacuum housing at both ends. The bearing gap has the same outer diameter at each of its two ends.
