The attachment part comprises two axial spaced support regions (821, 822) for performing a radial power transmission for a shaft. A running wheel-side seal is arranged on a running wheel-side of the support regions in a region of the piston rings and provided in form of a sealing gap (43) between bearing housings (30, 31) and the attachment part. A cavity (85) is axially formed between the support regions. An independent claim is also included for an exhaust-gas supercharger or turbine.",
