ABSTRACT:
A rotor support shaft for an open-end spinning rotor assembly is disclosed which is equipped on its free end with a supporting element which forms an essentially radially extending supporting surface for a vibrating ball of a step bearing. The supporting element is made of a material, preferably for a ceramic material, which has a higher hardness than steel. The supporting element is arranged in a receiving device concentric with respect to the axis of the shaft in such a manner that the supporting surface projects slightly from the front face of the shaft.
