Abstract

A support disk bearing (1) for an open-end spinning rotor (9) with support disks (4, 5) arranged in pairs, each of which has a hub body (14) made of a metallic material and a bearing ring (15) made of a polymeric material. On its circumference, the hub body (14) has a radial circumferentially extending profiling (20), between whose V-shaped center structure (21) and lateral ribs (22, 23) the free flanks (24, 25) of an M-shaped bearing ring (15) can be fixed, and which has a thickness (D) which is almost constant in cross section.
