Abstract: A mounting part for mounting an end of an axle on a projection of a housing, such as an axle in a vacuum-tight housing of a rotatable anode, is characterized by a sleeve section which can have radial play during assembly and engages a clamp arrangement to remove the radial play at the end of assembly of the section on either the end of the axle or the projection of the housing. The clamp arrangement is a bevel provided on the member being telescopically received in the section or on a ring which is telescopically received on the member being received in the section.

Abstract: An x-ray radiator has an x-ray tube disposed in a protective housing and a fastening means having a portion attached to the x-ray tube inside the housing, and a portion which extends through the housing to the exterior of the housing. The exterior portion serves as a fastener to attach the x-ray radiator to a mount. The x-ray tube, within the housing, thus becomes directly attached to the exterior mount, which improves the precision with which the specified position of the central ray of the x-ray beam emanating from the x-ray tube can be achieved.
