Zusammenfassung:	For the purpose of moving a sleeve (14) in the Z-direction, in a drive device of a coordinate measuring machine a master piece (6) which is connected to the sleeve (14) in a rotationally fixed fashion is guided on a screw (3). In order not to transmit a radial runout of the screw (3), the master piece (6) has a bearing surface (9) on the top side, and the sleeve (14) is seated with a support surface (20) via rolling elements (13) on the bearing surface (9). The rolling elements (13) provide the support surface (20) with play (21) in the direction radial to the axis of rotation of the screw (3).
