Abstract

An open-end spinning device (1) with a spinning rotor (3) whose rotor cup rotates at a high speed in a vacuum-loaded rotor housing (2) closable by a conduit plate (27). The spinning rotor (3) is supported with its rotor shaft (4) in the bearing nip of a support-disk bearing (5) free of axial thrust and positioned in axial direction by a magnet bearing (18). The direction of rotation (S, Z) of the spinning rotor (3) can be selectively set via the direction of the rotor drive (V or R). The conduit plate (27) comprises a receptacle (34) in which exchangeable conduit-plate adapters (12.sub.S or 12.sub.Z) can be fixed in coordination with the particular direction of rotation (S or Z) of the spinning rotor (3).
