ABSTRACT:
The invention relates to a rotary-anode X-ray tube comprising a plain bearing, notably a spiral groove bearing, which comprises a bearing shaft and a bearing shell which encloses the bearing shaft, contains essentially molybdenum and/or tungsten or alloys thereof, and consists of at least two bearing shell portions, a liquid lubricant being present between the bearing shaft and the bearing shell. The material consumption and the manufacturing effort for the bearing shell are reduced in that on the outer side of the bearing portions there are provided connection elements which consist of a weldable material, and that the connection elements are connected to one another by way of a welded joint.
