Abstract

A supporting-disk bearing, particularly for the shaft of an open-end spinning rotor, the shaft (1) being mounted in a wedge-shaped gap formed by supporting disks (4, 5), and the supporting disks (4, 5) having a running surface (40,50) consisting of an elastic covering against which the shaft (1) is pressed. The running surface (40,50) has at least one interruption formed by a recess and bridged by the line of contact of the shaft (1). The recess can be designed in various ways, but it is preferably groove-shaped. The wear of the running surface is reduced as a result of this design.
