Abstract

A bearing of a spinning rotor 3 of an open-end spinning apparatus, in which the rotor shaft is radially supported by means of support disks and is axially positioned by a magnetic bearing. The center axis 51 of the rotor 3 is offset relative to the center axis 50 of the static bearing component 27 of the axial bearing 18 in the direction of the bearing nip 56. In addition, at least in the region of the end of the axial bearing 18 toward the support disks 54, 54′, an engagement surface 40 with an anti-friction surface layer is provided, which supports the rotor 3, especially during rotor cleaning.
