Abstract

An aerostatic axial bearing (6) of an open-end spinning machine in which the bearing plate (601) of the axial bearing (6) is made of a permeable material, has a bearing plate (601) provided with one or several air channels (605), the task of which is to convey the air closer to the bearing gap (630) before it goes through the permeable bearing plate material. Thereby, the utilization of an additional choke can be avoided. Furthermore the mechanical properties of the holder bearing plate (601) are improved.
