Abstract
A rotor shaft of a spinning rotor has an annular magnet bearing component which is secured from the centrifugal force effective during the spinning process by means of a ring liner, for radially and axially supporting the rotor shaft, whereby the rotatable magnetic bearing component interacts with a stationary magnetic bearing component. The magnetic bearing component linked with the rotor shaft (4) of the spinning rotor (3) is configured as a slotted permanent magnet ring (32,42), thereby ensuring the deformability required for fitting a ring liner (6,7).
