ABSTRACT:
A process for assembling a linear motion bearing using a retainerless saddle assembly. Such retainerless saddle assembly is composed of a bearing body having escape-ball through holes, steel balls, and a pair of end caps. The claimed assembling process includes the steps of: (a) attaching one of the pair of end caps at one end surface of the bearing body; (b) providing raceways within the bearing body by a raceway spacer, a diameter of each of the raceways being slightly larger than that of each of the steel balls; (c) feeding the steel balls into the raceways and escape-ball through holes in the bearing body; (d) holding the steel balls positioned within the raceways by said raceway spacer such that the steel balls will not fall off from the raceways within the bearing body; (e) covering an open end of the bearing body by another one of the pair of end caps so as to form a saddle; and (f) thereafter sliding the saddle onto a rail such that the raceway spacer is displaced by said rail to form a retainerless linear motion bearing.
