摘要：A linear motion guide unit is disclosed in which a slider moves relatively of andalong a track rail by virtue of rolling elements of balls or rollers. The rolling elementsare allowed to recirculate from a load raceway formed between the track rail and the

slider to a non-loaded area composed of a turnaround formed in the slider tocommunicate with the load raceway, and a return passage formed in the slider tocommunicate with the turnaround. The return passage is encircled with a sinteredresinous member of porous texture. Lubricant absorbed and held in voids in the sinteredresinous member can be supplied over a prolonged period to the rolling elements,thereby lubricating the rolling elements to make the frictional resistance less, whichmight be encountered when the slider moves on the track rail, and ultimately helpingensure the improvement in durability.
