Abstract: An X-ray tube comprises a substantially cylindrical rotor having an anode target fixed thereto, a substantially columnar stationary shaft coaxially arranged inside the rotor with a bearing gap, a dynamic slide bearing having helical grooves and formed between the rotor and the stationary shaft, and a metal lubricant supplied to the grooves and to the gap. An axial bore is formed in the shaft in a manner to extend in the longitudinal direction of the shaft, and an insertion rod is inserted into the axial bore such that a space extending in the longitudinal direction of the shaft is formed between the inner circumferential surface of the axial bore and the outer circumferential surface of the insertion rod. The space acts as a lubricant reservoir for storing the metal lubricant.
