Abstract

An open-end spinning apparatus has a spin rotor (1) which, by means of its shaft (11) is supported by support plates (4), wherein as an abutment for the axially directed force on the spin rotor (1), an aerostatic axial bearing (6) is provided. The bearing surface (115) of the spin rotor (1) operates together with a bearing plate (63) of the axial bearing (6). The bearing surface (115) or the bearing plate (63) are comprised of a construction material of polyimide. Advantageously, the polyimide is combined with an additive, namely graphite, for instance.
