A bearing bush system includes a bearing bush of polyamide that is held on an outer steering shaft with a stopping collar and on the free face of which the one-piece sealing element of thermoplastic elastomer that seals statically with a ring seal as well as dynamically with sealing lips is held in a form-fitting fashion by means of watchtower-like denticulated ribs provided on both sides. The bearing bush system of two plastics forms a single component, requires low manufacturing expenditures, can be easily assembled and also ensures a reliable seal.

The invention claimed is: 1. A bearing bush system for a two-part steering shaft that serves for producing an axially movable and sealing connection between an outer steering shaft and an inner steering shaft, the bearing bush system comprising:a bearing bush;a one-piece static and dynamic sealing element; anda covering cap;wherein the bearing bush has a face, comprises a hard plastic, is provided with a stopping collar, and is connected on the face to the one-piece static and dynamic sealing element;wherein the one-piece static and dynamic sealing element comprises flexible plastic material and seals statically and dynamically via a shrink denticulation, the shrink denticulation interlocking in a form-fitting fashion and simultaneously supporting the flexible plastic material;wherein a peripheral inner limb of the one-piece static and dynamic sealing element is provided as a dynamic seal and features a first sealing lip; andwherein a peripheral outer limb of the one-piece static and dynamic sealing element overlaps a lateral surface of the stopping collar, contacts the face of the outer shaft, and acts as a static ring seal.
