Abstract
In the present invention, the space between consecutive rollers and the relative positions between parts are preserved by inserting a flexible zigzagged strip between the rollers and the inner race and/or the outer race, wherein loops separate the rollers instead of cages, which take up room in the anti-friction bearing. The same concept can be applied to linear guides that use rollers instead of slide guides. The circumference of the rollers can be reduced to reduce the width of same and increase the number thereof in short-stroke linear motion guides. Additional small-diameter rollers or small strips can be used inside the loops to prevent the crushing thereof. The space between consecutive rollers and the relative positions between the parts can be preserved by means of other methods, by using connecting rods and/or a rack-and-pinion mechanism and small gears attached to the rollers.
