Abstract

In a rotatable anode (4) of an X-ray tube, a heat transfer between the rotating disc of the anode (4a) and the second bearing element (11) is achieved by providing a contact material (14) within a gap (16a, b) between the anode disc (4a) and the second bearing element (11). Contact elements (15) protrude from the second bearing element (11) into the contact material (14), thus allowing a heat transfer from anode disc (4a) to second bearing element (11) via contact material (14) and contact element (15).
