The bearing in an X-ray tube comprising a liquid metal lubricated helical-groove bearing is provided with a push-pull bearing at one or both end faces of a bearing member. Consequently, the bearing member need not be further secured so that, notably in the case of suitable cooling of the anode disc and the bearing, extremely precise positioning of the radiation object point in the tube can be ...

the bearing geometry, bearing kine-matics and lubricant, the bearing materials are of paramount impor-tance. It is thus not difficult to see that the design of lubricated sliding bearings can be quite complex. Complexity should not, however, be allowed to act as a deterrent to tackling a bearing design because the rewards for a good design are

These alloys, put on the the market under different trades names. have a low efficient of thin-film-lubrication friction, about 0.005; and like Babbitt, they do not score a journal when lubrication fails. The allowable pressure is 1,000 to 5,000 psi. In order to obtain a good copper-lead bearing alloy, it must be casted centrifugally. Plastics:
