A gas-static and gas-dynamic radial bearing assembly includes a shaft having a supply line extending in the interior thereof for bearing gas. The shaft has a portion in the form of a porous sintered body. A bearing has a given bearing length, part of which is occupied by the porous sintered body. The bearing has a bearing box divided into individual segments partly overlapping one another at given regions. Spring elements in the vicinity of said given regions spread said segments apart.

Gas-static and gas-dynamic bearing

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.
