The invention relates to a safety bearing for retaining a rotor shaft (4) of a machine (1), wherein the safety bearing (2) comprises a first carrier body (7) rotating about a virtual geometric center line (M) and roller bodies (5), wherein each roller body comprises a region (19) that is located between the center line (M) and the first carrier body (7), wherein the roller bodies (5) are each connected in a rotatable manner to the first carrier body (7) via a shaft (6). The invention creates a safety bearing (2) 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.
