Abstract: The top foil (12) of the hydrodynamic fluid film journal bearing (10) carries opposing tabs (23, 25) at the side edges adjacent the free end (17) thereof and extends radially outward to fit adjacent to the side edges (19, 21) of the intermediate foil (14) and the ends of the key (18) when rolled into a cylinder and inserted into the bore of sleeve (24) to prevent skewing of the top foil. In another embodiment, skewing is prevented by incorporating opposing tabs (37, 39, 50, 52) at the free ends (31, 54) of the top foil (12a) and intermediate foil (14a) that project through predetermined sized slots (40, 42) formed in the side edges (44, 46) at the fixed end of intermediate slot (14a). The tabs overlie the side edges of the intermediate foil (14b) and bump foil (15) when rolled into a cylinder and prevent skewing and enhancing journal bearing performance.
