Abstract

The present invention relates to a bearing for an open-end spinning rotor. The latter is driven at its rotor shaft by means of a tangential belt in a predetermined direction and is supported in a nip which is formed by at least two bearing disks capable of being driven by the rotor shaft. A bearing disk (at least one) leads in relation to the drive direction of the tangential belt rotating into the nip, and another bearing disk (at least one) trails in relation to the drive direction of the tangential belt rotating out of the nip. The axis of the bearing disk (at least one) rotating into the nip is at a specified distance from the plane which goes through the rotor shafts of the spinning rotors of several adjoining open-end spinning devices. This distance is being smaller than the distance between the axis of the bearing disk (at least one) rotating out of the nip and the rotor shaft plane. A plane going through the axes of the bearing disks forms an acute angle between 5° and 15° with the plane going through the axes of the spinning rotors.
