ABSTRACT:
An open-end spinning rotor (3) is supported by its rotor shaft (4) in a spinning-rotor bearing (5) with the rotor shaft (4) detachably connected via a coupling device (29) to a rotor cup (26) such that the rotor shaft (4) remains supported in the spinning-rotor bearing (5) when the rotor cup (26) is removed. The coupling device (29) comprises a magnetic device (30) for fixing rotor shaft (4) and rotor cup (26) axially relative to one another and a mechanical rotational safety mechanism (31) for fixing rotor shaft (4) and rotor cup (26) radially relative to one another.
