Abstract: A bearing system includes a bearing housing that includes a sleeve and a mounting structure for connecting the bearing system to a compressor housing. The sleeve has a radial inner surface that defines a cylindrical bore, and includes a locking feature located along the radial inner surface. The mounting structure is located radially outward from the sleeve. The bearing system also includes a foil bearing assembly positioned within the cylindrical bore. The foil bearing assembly includes an outer foil, an inner foil, and a bump foil positioned between the outer foil and the inner foil. At least one of the outer foil and the inner foil includes a bearing retention feature cooperatively engaged with the locking feature to maintain the foil bearing assembly within the bearing housing at a fixed rotational position.
