Abstract
The invention relates to a safety bearing for retaining a rotor shaft () of a machine (), wherein the safety bearing () comprises a first carrier body () rotating about a virtual geometric center line (M) and roller bodies (), wherein each roller body comprises a region () that is located between the center line (M) and the first carrier body (), wherein the roller bodies () are each connected in a rotatable manner to the first carrier body () via a shaft (). The invention creates a safety bearing () with which the likelihood of an occurrence of a backward-whirl is considerably reduced as compared to the safety bearings known from the prior art.
