Bearing arrangement for an open-end spinning device

摘要

An open-end spinning device with a spinning rotor is supported by a shaft in a bearing arrangement. An axially rearwardly directed force is exerted on the rotor shaft in operation of the spinning device. The end of the rotor shaft bears against an aerostatic bearing which includes a bearing surface oppositely facing the end of the rotor shaft made of a carbon material. The rotor shaft has a bearing surface defined on the end thereof opposite the aerostatic bearing which is made at least in part of a carbide material.
