The invention relates to a bearing arrangement (1), comprising a driven shaft element (2) which is supported by at least two roller bearings (3, 4), wherein the roller bearings (3, 4) are arranged at an axial distance (a) along an axis (A) and wherein an actuator element (5) is arranged by which the axial pre-load between the two roller bearings (3, 4) can be influenced. To adapt the pre-load in the roller bearings depending on the drive torque of the driven shaft element in a simple but effective way the invention is characterized in that the actuator element (5) comprises a first axial end section (6) and a second axial end section (7), wherein a plurality of beam elements (8) extend between the first and second axial end sections (6, 7), wherein the beam elements (8) are arranged along an outer circumferential surface (9) of the actuator element (5) and wherein the beam elements (8) are running along a helical curve or straight line (10) between the first and second axial end sections (8, 9).
