ていることを特徴とする、回転陽極形Ｘ線管。 It consists of an anode part and a cathode part that are vacuum-enclosed in an envelope, and the cathode part has a focusing electrode that supports the filament and focuses the electrons emitted from the filament. In a rotating anode X-ray tube that has a disk that collides with focused electrons and a rotor that is directly connected to the disk to rotate the disk and dissipate heat, the bearing that supports the shaft of the rotor is an inner ring that is in direct contact with the rolling elements. Alternatively, a rotating anode X-ray tube is characterized in that it has a recess at a position away from the transfer surface of the outer ring, and a solid lubricant such as lead or graphite is embedded in the recess.
