ABSTRACT:
The linear motion rolling guide unit includes a track rail, a casing slidable with respect to the track rail, end caps mounted to the ends of the casing, and flow regulating valves installed in oil grooves formed in the end caps. When the linear motion rolling guide unit is used in an inclined condition with the right side tilted downward, the flow regulating valves may be turned clockwise to limit the flow of lubricating oil to the raceways on the right side. This makes the amounts of oil supplied to the left- and right-side raceways equal even when the linear motion rolling guide unit is used in other than a horizontal attitude, assuring good lubrication.
