Abstract

The present invention relates to a ball coupler for use with ball screw and linear rail comprising spacer members, guidance members and connecting links. The spacer members are arranged between two adjacent balls to separate the balls and; prevent a mutual contact between the balls. The guidance members that are in the form of two strips located on opposite sides of the balls connect the spacer members on opposite sides of the balls in order to maintain the ball within an area formed by the guidance members and spacer members. The connecting link connects two adjacent spacer members between adjacent balls. The width of the connecting link in a direction of a connecting line between two guidance members is smaller than the overall height of the connecting link in a direction perpendicular to the connecting line, so that the connecting link has distinguished bending characteristics toward the connecting line.
