ABSTRACT:
A rotary-anode X-ray tube including a sleeve bearing with a stationary and a rotatable bearing portion having facing bearing faces, at least one of which is provided with a groove pattern, has a lubricant which is liquid at least in the operating condition present between the bearing faces. A reduction of bearing wear is achieved by addition of a solid having a low sliding friction to the lubricant.
