An x-ray tube (1) includes a heat shield (130) which intercepts heat radiating from an anode (10), thereby reducing the temperature of a bearing assembly (62). The heat shield includes outer and inner concentric cylinders (132, 134) spaced from each other by a vacuum gap (138). The heat shield and a stationary portion (114) of the bearing assembly are both connected to a cold plate (150) so that heat is not conducted from the cylinders to the bearing assembly but is instead carried away by the cold plate to the surrounding cooling oil.
