Abstract
A hydrodynamic thrust bearing has an annular plate, a plurality of bearing foils, and a plurality of bumper foils. The annular plate has a first face and a second face opposite the first face. The bearing foils have an arcuate shape and are joined to the first face of the annular plate. The bumper foils have an arcuate and corrugated shape and are joined to the second face of the annular plate. A method of making a hydrodynamic thrust bearing includes joining the bearing and bumper foils to the annular plate with integrally-formed spacers in which each bumper foil corresponds to a bearing foil.
