ABSTRACT:
A spindle drive for measuring devices comprises a threaded spindle with a nut threadably engaged on the spindle and with one of them being rotatable to cause displacement relative to the other along a longitudinal direction in relation to the spindle. A nut carries a slide portion with vertically extending posed blind bores carrying bushings with ball races therein. A measuring carriage is affixed and forms part of a support portion which extends over the slide and the measuring carriage portion extend below the slide. A drive pin is carried by the support portion and the measuring portion and it is confined for movement within the respective bushings. A screw bolt is connected between the support portion and the slide and it may be threadably adjusted to permit vertical adjustable positioning of the slide relative to the measuring carriage and the support portion.
