ABSTRACT:
The linear motion rolling guide unit has a top seal secured to the casing which comprises a pair of lip seals that are in sliding contact with side areas of the upper surface of the track rail. The lip seals each have a pair of lip portions that incline from a base portion outwardly toward the sides of the casing. Because the lip portions are spaced a predetermined distance from each other, their sealing actions are not affected by each other, effectively preventing further ingress into the raceway grooves of foreign matters that have entered into the slider. When the pressure in the raceway grooves is increased by the supplied grease, the lip portion on the outer side is pressed with an increased force against the upper surface of the track rail, effectively preventing leakage of the grease.
