A rotary bearing assembly having a preset breaking point, particularly for a rotor of a turbo engine, includes a rotary bearing arranged between a nonrotating bearing carrier housing and a bearing carrier rotating about a rotational axis, the rotary bearing being fixed radially and axially at its outer bearing ring via a first tangential plane and a second tangential plane in the nonrotating bearing carrier housing. At predetermined stress, a breaking arrangement for the formation of a preset breaking point is provided, which is arranged in the first tangential plane and the second tangential plane, concentric with the rotational axis, between the outer bearing ring and the nonrotating bearing carrier housing.
