Spinning rotor () for an open end rotor spinning machine comprising a rotor shaft (), a rotor cup (), which has an opening (), an inner chamber (), a rotor groove (), a conically widening slide wall () extending from the opening () to the rotor groove () and a rotor base () arranged opposing the opening () and designed with a bore (), through which the rotor shaft () extends at least partially. The rotor shaft () is connected by means of a connection element () to the rotor cup () and the rotor shaft () and rotor cup () comprise a common rotational axis (). The rotor shaft () and the rotor cup () have connection means (), which are at least partially surrounded by the connection element () configured as a cast part, so a positive connection of the rotor shaft () to the rotor cup () can be achieved.
