Abstract
The supporting disks for supporting disk bearings of open-end spinning rotors comprise a tire or ring with damping properties, as well as an essentially cylindrical running surface. In order to avoid heat build-up, the running surface is interrupted by two grooves, thus dividing the running surface into one inner and two outer sectional surfaces. The outer sectional surfaces are each wider than the inner sectional surface by 20 to 40%.
