ABSTRACT:
For an aerostatic bearing (6) of an open-end spinning rotor, in which the bearing material consists of a wearable material, a wear indicator (9) is provided on the bearing plate (601) of the axial bearing (6) so that the state of wear of the axial bearing (6) can be checked by simple optical inspection. The wear indicator (9) can be integrated into the running surface (610) and be made e.g. in the form of a blind bore (91), so that the presence of the bore indicates that the wear lies still within the admissible limits.
