Abstract
A method for producing porous bearing shells with a compacted surface for gas-static bearings from sintered hollow blanks includes heating a blank with an inside diameter smaller than a rated diameter of a bearing and slipping the blank in the heated state onto a mandrel having an outside diameter equal to the rated diameter of the bearing. Subsequently the blank is cooled to the operating temperature of the bearing. The blank is reheated and the blank is finally pulled off the mandrel.
