ABSTRACT:
A static pressure gas bearing is incorporated in a housing wherein a slotted groove with a small volume and a throttling control valve are positioned close together. Compressed gas is injected onto the bearing surface from the slotted groove. This configuration provides a static pressure gas bearing in which it is difficult to develop self-induced vibration.
