。[Claims for Utility Model Registration] An extended guide rail with symmetrical axial ball rolling grooves on both sides, and a ball rolling groove of the guide rail that is movably straddled over the guide rail. A ball rolling groove facing the groove is provided on the inner surface, and a linear ball return passage parallel to this is provided within the wall thickness.
a slider having semi-doughnut-shaped curved paths at both ends that communicate the ball return path and the ball rolling groove; A ball row consisting of a large number of freely inserted balls,
In a linear guide device that is installed with an inclination that causes a difference in height between the ball rows on both sides of the guide rail, a vertical oil supply port is provided at the upper side edge ridge of the slider, and a vertical oil supply port is provided at approximately equal angles from the oil supply port. A linear guide device characterized in that a branch oil passage is provided in the slider, one of which communicates with the ball return passage located on the upper sleeve portion and the other communicates with the ball return passage located on the lower side. refueling structure.
