PURPOSE:To mitigate the slip resistance between a track groove and a rolling element and the slip resistance between the rolling element and a holder generated when the delay or advance of the rolling element is forcefully pressed by a pocket in the track groove between a table applied with a pre-load and a bed. CONSTITUTION:Multiple pockets 3 each having a long hole with the width and the length in the rolling direction larger than the diameter of the rolling element 1 to be held are bored on a holder 2 holding the rolling element 1 of a finite direct acting rolling guide unit. |
