Abstract

Proposed is a support disk bearing for an open-end spinning rotor. The support disk possesses a body, which, on its circumferential surface, is designed to receive a cover layer. The cover layer is comprised of rubber, in particular nitrile rubber (NBR). In an advantageously favorable formulation, the cover layer contains an additive for the reduction of its electrical resistance.
