ABSTRACT:
Provided is a hydrostatic gas bearing capable of assembling bearing units without deteriorating perpendicularity to an axis of a cylindrical housing even when the housing is distorted. The housing having a cylindrical hole through which a rotary shaft penetrates, cylindrical hydrostatic bearing units and a spacer of which axial end surfaces are perpendicular to a center axis of the spacer, and a cover which is mounted to the other end of the housing and presses a hydrostatic bearing unit via an O-ring. The hydrostatic bearing unit does not incline, since the end surface of the hydrostatic bearing unit is fitted tightly to an end surface of the spacer by the pressure from the O-ring, even when the other end of the housing is not perpendicular to the center axis of the housing and the cover is inclined.
