ABSTRACT:
A rolling element chain system for a linear guideway comprises a slide rail, a slide block, a plurality of rolling elements and a rolling element chain. The circulating path of the slide block is interiorly provided with a guiding groove with a width C, and the rolling elements roll within the circulating path and are confined by the rolling element chain. The rolling element chain has a plurality of spacers for separating the rolling elements from one another and linking portions with a thickness t for linking the rolling elements with one another. The spacer at each end of the rolling element chain has a retaining capacity B for holding the corresponding rolling element. The above structure satisfies the relation: C<t+B/π.
