Rolling bodies (13) are arranged between the stator-side bearing ring (11) and the rotor-side bearing ring (12). Transducers for determining the position of the stator-side bearing ring (11), and actuators (21) for influencing the position of the stator-side bearing ring (11), are associated with the stator-side bearing ring (11).
