An axial bearing for a spinning rotor of an open-end spinning machine includes a static bearing component having axially polarized permanent magnet rings delimited on both sides by ferromagnetic pole disks arranged in a bearing housing, the static bearing component interacting with a dynamic bearing component formed by ferromagnetic webs arranged on a rotor shaft of the spinning rotor. Each pole disk includes a disk ring, a central opening, a vertical axis, and a horizontal axis. The disk ring includes an area of reduced ferromagnetic material on an inner circumference thereof at the vertical axis as compared to a remaining inner circumferential area of the disk ring.
