Abstract An apparatus for converting rotary motion into axial motion includes a spindle with an external contour and a nut with an Internal profile end interposed contoured rollers which have two different contours, one of which produces an axial connection with the contour of the spindle, and the other of which produces a corresponding axial connection with the contour of the interior of the nut. It is preferred that the contour on the interior of the nut be in the form of relati- vely coarse grooves of V-shaped cross section, with one simple thread on the exterior of the spindle. Coarse grooves corresponding to and fitting the coarse grooves on the interior of the nut, alternating with a number of fine grooves corresponding to the fine simplex thread on the spindle, are provided on the outside of the rollers that are disposed between the spindle and the nut.
