Abstract: The present invention is mainly to provide an improved structure for linear guideway, which in general contains: an unlimitedly extendable guideway, a moving slider along the guideway, a slide way installed inside the slider for the movement of the rolling objects, an end cover installed at the end of the slide way for the rolling objects to circulate; among which a lubricating structure is installed longitudinally inside the slider and mainly contains an oil reservoir inside the slider, which oil reservoir extends to the two ends of the slider and connects to the slide way and has a diversion device inside, which diversion device is rather tough and long enough for contact with the most surface area of the rolling objects (FIG. 3).

Abstract: A linear guide way structure comprises a guide rail, a slider, and two end cups. The slider has two ends each defining a ball return hole having a first-end-opening, and a ball groove having a second-end-opening. The adjustable end cup is provided with two ball direction changing paths each having a first-mating-end-opening abutting the first-end-opening of the ball return hole, and a second-mating-end-opening abutting the second-end-opening of the ball groove. The adjustable end cup is provided with a plurality of adjusting slits, and at least one of the adjusting slits has a determined depth so that the adjustable end cup is made flexible, thereby adjusting the distance between the two first-mating-end-openings of each of the two ball direction changing paths of the adjustable end cup, so that the first-mating-end-opening can be exactly engaged with the first-end-opening of the ball return hole.
