An apparatus including a shaft, with a first and a second angular contact bearing axially disposed along the shaft to provide support for the shaft in a first and a second axial direction, respectively. The second axial direction is substantially opposite the first axial direction. A preload device exerts a preload force onto the angular contact bearings, which place the angular contact bearings into a maximum preload condition. An actuator device, acting in opposition to the preload device, reduces preload from the maximum preload condition to a desired preload condition. The preload device and the actuator device act directly through an axial displaceable race of the angular contact bearing, instead of through the rolling elements of the bearing.
