Abstract

An X-ray tube for generating X-radiation includes a rotary structure having a rotating anode, a stationary structure for rotatably supporting the rotary structure, and a hydrodynamic bearing which is arranged between the rotary structure and the stationary structure. The bearing includes a gap between the rotary structure and the stationary structure, a stabilizer configured to stabilize dimensions of the gap with respect to distortions because of thermo-mechanical causes.
