The device i.e. turbocharger (1), has a shaft (4) rotatably supported at a radial slide bearing (5), and a flow opening (9) formed for supplying and/or discharging fluid to a shaft bearing area (7), where the bearing has an annular groove. The shaft has outer sections in the bearing area, where the outer sections run in a circumferential direction. The outer sections axially limit an inner section, where one of the outer sections has a micro structure at a surface. Length of the micro structure runs parallel to a structure direction, where the structure is manufactured with a laser process. |
