A spherical and plane hydrostatic bearing of the outlet restrictor types rigidly combined in a compact spindle structure comprising a central housing with finished surfaces and bores, a shaft with thrust plate and truncated hemispherical bearing surface at opposite ends, and means for bringing fluid under pressure to the inner peripheries of the matched bearing surfaces to flow radially or longitudinally outward to the outer peripheries where clearance is slightly restricted. The bearings are self-adjusting for spacing and alignment, non-interacting with regard to individual degrees of freedom, and together define the spindle axis as the normal to the plane of the thrust bearing through the center of the spherical bearing.
