A bearing bush system comprises a bearing bush (3) of polyamide that is held on an outer steering shaft (1) with a stopping collar (2) and on the free face of which the one-piece sealing element (7) of thermoplastic elastomer that seals statically-with a ring seal (14)-as well as dynamically-with sealing lips (10, 11)-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.
