ABSTRACT:
There is disclosed a ball screw integrated type linear movement guiding unit which achieves a stable, smooth operability, and can meet with a high-load and high-rigidity application. Each of ball return passageways which respectively provide ball-circulating passageways of a ball screw system and a linear movement guiding system in the unit is constituted by an axial through hole much larger in diameter than a ball, and a cylindrical member of a synthetic resin which has an inner diameter generally equal to the diameter of the ball and is press-fitted in the through hole. With this construction, the rolling of the balls is effected smoothly. Further, even if the length of a nut is increased to meet with a high-load and high-rigidity use, the ball return passageway can be easily formed.
