The invention relates to an X-ray rotating anode whose body has radial recesses which cross under the path of the focus spot and those which cut through the path of the focus spot. These recesses are used to compensate for stresses which are caused during the production of X-ray radiation by the heating of the anode which occurs at the same time. However, in the case of such unstressed anodes, it is still desirable to increase the load capacity. According to the invention, this is possible in that the holes (15) are broken towards the focus spot path (9, 10) and the plate (8) is a ring which is at least 6 mm thick, corresponds approximately to the width of the focus spot path and has a heat-insulating hub (16, 12) towards its rotation axis (11). An X-ray tube which is equipped with a rotating anode according to the invention is particularly suitable for use in medical X-ray diagnosis. <IMAGE>
