ABSTRACT:
An X-ray tube comprising a rotary anode which is journalled in a helical-groove bearing is constructed so that the axial median plane of the rotary anode system is approximately coincident with the axial center of the helical-groove bearing. The bearing block for the anode system is connected to the tube base preferably via a connection whose rigidity is adapted to the weight, the geometry and the weight distribution of the anode system. The connection allows for cooling of the bearing block by means of a cooling liquid.
