Abstract: The present invention relates to hydrodynamic bearings, X-ray tubes, X-ray systems, and a method of manufacturing a hydrodynamic bearing for an X-ray tube. The rotor of a hydrodynamic bearing is supported, in steady-state operation, by the pressure of lubricant which is pumped through grooves in the rotor.

Providing special coatings on the bearing surfaces can ameliorate this effect.
