Abstract
For a bearing arrangement of an open-end spin rotor, which is rotatably set in the 'V' between circumferential rims of support disks, one or more of the support disks (14), which bear the open-end spin rotor, has a circumferential cleaning groove (3). The cleaning groove (3) can be a self closing, endless groove, which runs over the contact surface of the support disk (14), wherein it generally does not run parallel to the edges of the support disk (14). Such a meandering groove formulation of the support disk circumference assures that no deposits of impurities can accumulate on the rotor shaft.
