A fluid bearing assembly, e.g., air or gas, of the hydrostatic or hydrodynamic type, for use as a spindle and the like, includes spaced journals mounted on a shaft for rotation therewith. The housing includes spaced support bearings cooperating with the journals to form a gas gap therebetween. The support bearings are resiliently mounted in the housing for axial, radial and angular movement through the use of continuous resilient support elements positioned between the housing and the support bearings and continuously in contact with each. The resilient support elements are preferably self-energizing and comprised of relatively low coefficient of friction materials to reduce the friction of the system thus allowing rapid adjustment of the bearing in response to loads on the shaft. Various details are described with respect to the various structures illustrated, including the details of an air bearing spindle assembly of relatively light weight and capable of operating at speeds in excess of 100,000 RPM.
