Abstract

The present invention concerns a procedure for the reworking of a open-end spinning apparatus for a spin rotor, which is carried in the V-notch between support disks and is supported by a ball axial thrust bearing. Where the reworking is concerned, the bearing block of the open-end spinning apparatus is dismounted, the ball axial thrust bearing is removed from the bearing block and in accord with the invention, is replaced by an aerostatic bearing in the bearing block.
