ABSTRACT:
The disclosure concerns rotating-anode type X-ray tubes. According to the disclosure, the rotor is supported by passive magnetic bearings, the respective positions of which are such that the rotor is shifted in the direction opposite to that of the anode. The rotor is kept shifted by a thrust-bearing acts, at the same time, as an electrical conductor for the anode current.
