摘要

Actuator, in particular for a rear axle steering system of a motor vehicle, comprising a, an axially displaceable spindle (5) and a spindle drive, a housing (2) with at least one as a thrust bearing (15) formed means for preventing rotation of the spindle (5), wherein the spindle (5) at least one section with a spline shaft (14) and the thrust bearing (15) a bearing opening with a spline (17a, 18b) for receiving the spline (14), characterized in that said thrust bearing (15) as a split hub ring with a first hubs half (17) and a second hubs half (18) is formed, which along the longitudinal axis (a) of the spindle (5), as seen in the axial direction, are arranged one behind the other and in the circumferential direction by means of a fuel reservoir are braced against one another in the circumferential direction.
