Sealing ring e.g. shaft sealing ring, for use in exhaust gas turbocharger of internal combustion engine of motor vehicle, has groove combs running parallel to each other, where front side is provided with shark-skin-like microstructure
The sealing ring (5) has groove combs running parallel to each other, where an axial front side (8) of the sealing ring is provided with a shark-skin-like microstructure that is designed as a groove structure. The sealing ring is fixed at a housing (6) of an exhaust gas turbocharger and is engaged into a circumferential groove (7) of a shaft (1) of the exhaust gas turbocharger. The groove combs possess a pointed, wedge-shaped cross section.
