| abstract | A ball screw having a longer life is provided. A screw shaft having a helical male screw groove formed on an outer peripheral surface, a nut having a helical female screw groove formed on an inner peripheral surface opposed to the male screw groove, and a screw shaft formed between the male screw groove and the female screw groove. A plurality of balls movably interposed, a retaining piece disposed between adjacent balls as necessary, and a ball circulation for scooping up the ball at one end of the ball rolling space and moving the ball to the other end. And a ball screw enclosing a grease composition containing a conductive substance in a ratio of 0.1 to 10% by mass. [Selection diagram] Fig. 1 |
