Abstract

A magnetic bearing is disclosed for an open-end spinning rotor having a shaft supported in a wedge-like gap formed between at least one pair of support rollers. The bearing comprises a housing for receiving the shaft, a magnet disposed in the housing to extend radially relative to the shaft, and a magnet disposed on and radially extending from the shaft axially adjacent and at a spacing from the magnet in the bearing housing. The magnets have respective poles of the same magnetic orientation disposed to face and thereby repel one another. According to the invention, a coupling connects the shaft and the magnet disposed on the shaft, the coupling being releasable in response to an axial force exerted on the shaft.
