Abstract

PURPOSE: In the bearing device formed of the gap part between the bearning part and the wall of the oil tank, for example the bearing device used for an uranium concentrating centrifugal machine, the generation of cavitation at the bearing part is prevented by a simple constitution, and a good damping characteristic is obtained.
