Abstract
An open-end spinning device () with a spinning rotor () whose shaft end () is supported by an aerostatic axial bearing () with an air gap () located between a bearing plate () of the axial bearing () and the shaft end (). The aerostatic axial bearing () comprises a bearing plate () and a throttle device () made from a porous graphite material placed before the bearing plate (). The throttle device () is an stamped pressed, tablet-shaped molding with largely homogenous porosity. In a process for manufacturing an aerostatic axial bearing () for a spinning rotor () of an open-end spinning device (), a throttle device () made from a porous graphite material is placed before the axial bearing (). The throttle device () is stamped pressed in a press tool as a tablet-shaped molding.
