An electric auxiliary power steering system for a vehicle, comprises a rotating component driven by a servomotor and comprises a rolling bearing for axially and radially supporting the component in the frame. At least one inner race or one outer race of the rolling bearing is split into two race parts along a parting plane that runs approximately perpendicular to a longitudinal axis of the rotating component, the two parts being axially spring-loaded against one another, wherein the ends of the race parts facing one another are aligned at an angle from the radial outer side thereof to the radial inner side thereof, and an element with a conical cross section and having a higher coefficient of thermal expansion than the coefficient of thermal expansion of the outer ring or the inner ring is placed between the ends so that when heat is introduced, the element expands and the race parts are able to move toward one another, and when the element cools the race parts can move apart axially.
