Abstract
An X-ray tube bearing assembly has a first X-ray tube shaft with first and second ball-bearing raceway surfaces which are integral with (i.e., either monolithic portions of or fixedly attached to) the first shaft and has a second X-ray tube shaft with a third ball-bearing raceway surface which is integral with the second shaft. A ball-bearing race, which is non-integral with (i.e., neither a monolithic portion of nor fixedly attached to) the two shafts, has a fourth ball-bearing raceway surface. A first set of ball bearings is located between the first and third raceway surfaces, and a second set of ball bearings is located between the second and fourth raceway surfaces. Preferably, an anode target surface is attached to the first shaft, and a mechanism is provided to preload the ball-bearing race.
