ABSTRACT:
An x-ray tube includes an envelope defining an evacuated chamber in which an anode assembly is rotatably mounted to a bearing assembly and interacts with a cathode assembly for production of x-rays. The bearing assembly includes a bearing housing and a plurality of bearings disposed on an outer surface of the bearing housing. A cooling channel is defined within the bearing assembly and directs cooling fluid such as oil across an inner surface of the bearing housing. As the cooling fluid flows adjacent the inner surface of the bearing housing, heat from the bearing housing is absorbed by the cooling fluid thereby reducing the heat transferred to the bearings.
