A rotating anode bearing housing includes an x-ray tube frame (106) that
has a vacuum chamber (108). An anode (110) resides within the vacuum
chamber (108) and rotates on a shaft (114) via a bearing (117). The
bearing (117) is attached to an interior surface (126) of the x-ray tube
frame (106). The bearing (117) transfers thermal energy from the shaft
(114) to the x-ray tube frame (106).
