ABSTRACT:
An arrangement for an open-end rotor spinning comprises a spinning rotor which is radially supported with a rotatable shaft in a wedge-shaped gap of two supporting disc pairs and axially in a step bearing housing. The shaft can be pulled out from its support from the operator's side of the arrangement and inserted again into the support. For the purpose of cleaning the gap between the back supporting disc pair and the front face side of the step bearing housing, a tube is provided having an entry opening at the operator's side of the arrangement and leading to the area of the step bearing housing and aligned against the shaft with an opening.
