Abstract
According to one embodiment, a rotating anode X-ray tube includes a cathode, an anode target, a sliding bearing including a rotating unit, a stationary shaft, and a lubricant, and a vacuum tube. The rotating unit includes a bearing member which is formed to extend along the rotation axis and which is located to surround the stationary shaft. The stationary shaft is formed of a tungsten carbide alloy. The bearing member is formed of SKD11.
Claims2
