Step bearing for axial support of an open-end spinning rotor

摘要

To improve the known step bearings for the support of open-end spinning rotors it is proposed to design the bearing body with a machine-side support and a rest for the spinning rotor. According to the invention, an even bearing surface (2) constituting one end of the bearing body (11) is provided as the rest for the spinning rotor. The even bearing surface (2) is preferably designed as a bearing plate 23 of an aerostatic step bearing (1) capable of being subjected to compressed air.
