ABSTRACT:
A ball screw integrated type linear movement guiding unit including a guide rail, a male-threaded screw shaft, a nut having a female-threaded screw hole formed therein and end caps fastened to the opposite end surface of the nut, wherein a plurality of first through holes are drilled through the nut in the axial direction for building a linear movement guiding system in cooperation with ball rolling grooves on the guide rail and the nut, a plurality of second through holes are drilled through the nut in the axial direction in parallel with the first through holes for building a ball screw system in cooperation with ball screw grooves in the screw shaft and the ball screw grooves on the screw shaft, a plurality of first curved passages are formed in each of the end caps while building the linear movement guiding system in cooperation with the first through holes, and a plurality of second curved passages are formed in each of the end caps while building the ball screw system in cooperation with the second through holes. Each of the first and second curved passages is built by forming a semicircular recess having a large diameter and a semicylindrical recess having a small diameter in each of the end plates and then fitting a semicylindrical return guide to the semicylindrical recess.
