ABSTRACT:
The rotating anode x-ray tube has a composite outer bearing made from two rings of a high hot-hardness material and a spacer between the two rings made of a constant coefficient of thermal expansion material. The spacer is welded to the two rings providing the composite outer bearing. One inner bearing race is formed from the shaft and the other inner bearing race is a one-piece inner race mounted on the shaft while the two rings have the corresponding outer races.
