A spinning rotor for open-end spinning machines and a method for balancing the spinning rotor in the course of a single clamping process by removing material from a cylindrical-shaped section of the collar ( ) of the rotor cup ( ) to form an identification mark ( ) thereon sufficiently to offset an imbalance and equalize the mass of the rotor. The mark ( ), which preferably consists of a combination of a graphic symbol ( ) and lettering ( ), is used for identification and information.
