摘要

The invention relates to a spindle intended to be assembled with a slider, to form a linear actuator, which transforms rotational movement of either the spindle or the slider into translational movement of either the slider or the spindle. In order to facilitate reduction of the play between a thread of a spindle and a corresponding thread of a slider to be guided by the spindle at reduced production and assembly costs, a spindle (10) for a linear actuator comprises an external thread (14) and a cutting portion (18) adapted to cut at least a part of a thread in a slider (12).
