Abstract: A lip portion of an end seal is born against a metallic core to make no interference against an end cap. The metallic core controls deformation of the lip portion to improve the close engagement of the lip portion with a guide rail. The lip portion is composed of an outside lip extending outwards and an inside lip extending inwards of the slider. A root portion where the inside and outside lips are merged together is secured to the metallic core in such a relation that the metallic core bears stress exerted on respective center lines of the outside and the inside lips. The metallic core is composed of a mounting portion having a mounting surface, a bent portion extending widthwise of the slider and biased or deflected more outward of the slider to prevent the lip portion from make any interference with the end cap.

Abstract: Lubrication for rolling elements is carried out in a turnaround passage in an end cap. An applicator nose to come into touch with the rolling elements has a molding density greater than in a lubricant reservoir plate to ensure proper and steady lubrication, with accompanying sustainable maintenance-free condition for lubrication. The lubricant reservoir plate impregnated with lubricant fits into a concavity inside the end cap. The applicator nose is integral with the lubricant reservoir plate and extends through a hole cut in the end cap to reach a turnaround passage to be exposed at a leading edge thereof to the rolling element to resupply the lubricant around the rolling elements.
