Abstract
A rotary-anode X-ray tube includes a sleeve bearing having bearing faces which are rotatable relative to one another in a direction of rotation and at least one of which is provided with a pattern of grooves. The service life of such a sleeve bearing can be prolonged by providing the grooves with a recess at their rearmost end, viewed in the direction of rotation.

A rotary-anode X-ray tube, comprising a sleeve bearing having bearing faces which are rotatable relative to one another in a direction of rotation and at least one of which is provided with a pattern of grooves, characterized in that a recess is provided at the rearmost end of the grooves, viewed in the direction of rotation for collecting abrasion particles, the depth of the recess being greater than the depth of the grooves.
A rotary-anode X-ray tube, comprising a sleeve bearing having bearing faces which are rotatable relative to one another in a direction of rotation and at least one of which is provided with a pattern of grooves, characterized in that a recess is provided at the rearmost end of the grooves, viewed in the direction of rotation, the depth of the recess amounting to approximately twice the depth of the grooves.
A rotary-anode X-ray tube, comprising a sleeve bearing having bearing faces which are rotatable relative to one another in a direction of rotation and at least one of which is provided with a pattern of grooves, characterized in that a recess is provided at the rearmost end of the grooves, viewed in the direction of rotation, the recess extending in the longitudinal direction of the grooves over a distance equal to from two to three times the groove width.
