ABSTRACT:
An aerostatic bearing is provided for the thrust bearing arrangement of the shaft of an open-end spinning rotor. This aerostatic bearing comprises a bearing plate, which forms a bearing gap with the end of the shaft. An axial thrust, directed against the bearing, is exerted on the shaft. The bearing plate is provided with bore holes for releasing air into the bearing gap. An adjustable ball cup is arranged at the bearing plate for adjusting the bearing gap. This ball cup preferably takes the form of a sliding body which has a spherically shaped surface and is held in a corresponding spherically shaped bearing support. After the open-end spinning rotor has been adjustable cup adjusts automatically so that the surfaces which form the bearing gap are disposed parallel to one another.
