An actuation device for a brake disc has a recirculating ball screw-nut screw assembly and a thrust bearing. The recirculating ball screw-nut screw assembly has a threaded shaft and a nut screw screwed onto the threaded shaft. The threaded shaft and the nut screw extend in direction of an actuation axis. The threaded shaft extends between a front end and a rear end of the threaded shaft. The nut screw receives a torque generatable by a gearmotor. A rotation of the nut screw with respect to the threaded shaft results in a translation of the threaded shaft with respect to the nut screw in the direction of the actuation axis. The thrust bearing provides a reaction rest for the nut screw in the direction of the actuation axis. The thrust bearing is positioned within an extension of the threaded shaft between the front and rear ends of the threaded shaft.
