Abstract
A sealing unit for a turbocharger for sealing a transition from a bearing housing into a compressor housing, and a method for producing a sealing unit of this type. The sealing unit includes a sealing bush which is designed for common rotation with a shaft of a turbocharger, a slide ring, and first and second groove rings. The first and second groove rings are designed for common rotation with the sealing bush and are arranged on the sealing bush. The slide ring is arranged between the first and second groove rings in the axial direction so that radially extending sealing gaps are formed on both sides of the slide ring between the slide ring and the respective groove ring.
