Abstract: 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.

Abstract: 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.

Abstract: To improve the crosstalk behavior of a multi-channel magnetic tape recorder with a rotating head wheel, whose magnetic heads receive signals through a rotating transformer, the leads between the magnetic heads and the corresponding transformer windings are shielded from one another. Advantageously, this shielding is made of small tubes of an efficiently electroconductive metal which, in another embodiment, can be securely connected electrically and mechanically with the rotational axis. For further improvement of the crosstalk characteristics, the shielding can also be connected in an electrically conducting fashion with the short-circuit rings located between the individual transformers.
