An electromechanical servo steering system with an electric servomotor having a motor shaft that drives a shaft which cogs with a helical gear. The shaft is arranged in a transmission housing and is mounted rotatably about an axis of rotation at its end near the motor in a bearing arrangement and is mounted pivotably in the transmission housing about a pivot axis which lies transverse to the axis of rotation. At least one spring element is provided which axial pretensions a bearing element that is pivotably movable with the shaft about the pivot axis, of the bearing arrangement in a spring-elastic manner against a bearing element that is arranged in a stationary manner in the transmission housing, of the bearing arrangement, wherein precisely two spring elements are provided which are arranged oppositely in the circumferential direction of the bearing arrangement.
