Abstract
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, a flat bearing surface constituting one end of the bearing body is provided as the rest for the spinning rotor. The flat bearing surface is preferably designed as a bearing plate of an aerostatic step bearing capable of being subjected to compressed air.
