ABSTRACT:
A rolling nut in combination with a smooth shaft includes a plurality of bearing-like roller cages surrounding the shaft and having internal surfaces in contact with portions of the outer surface of the shaft and is operative for transforming a rotary movement of the shaft into thrust movement of the rolling nut. The rolling nut is open and is provided with a base plate formed with a plurality of pocket-shaped recesses in which the roller cages are partially inserted. The base plate is formed with similar recesses at both sides thereof so that the roller cages can be repositioned on either side of the plate to selectively adjust the roller cages to the left hand thread of the shaft or the right hand thread of the shaft.
