Abstract
To convert a rotational movement into an axial movement, rolling or roller bodies (2') are seated by way of a plurality of guide rings (5) and bearings (6) disposed between the guide rings (5) and a spindle nut (3'). The rolling or roller bodies (2') are fixedly spaced relative to the spindle nut (3') and one another, so an axial reception of a force or torque by the spindle nut (3) is transmitted through the rolling and roller bodies (2'), the guide rings (5) and the bearings (6), and, via the rolling or roller bodies (2'), the guide rings (5) and the bearings (6), a rotational movement of the spindle rod (1) is converted into an axial movement of the spindle nut (3'), or vice versa, that is free from pitch errors.
