ABSTRACT:
A bearing assembly for facilitating relative sliding rectilinear motion between a first and second part which includes a rail body adapted to be connected to one part, and a ball retainer means adapted to be connected to the other part. The rail means has opposed longitudinal edge portions defining a track, and the retainer means comprises a pair of complementary members defining an endless raceway, and which raceway has an outer edge portion disposed contiguous to the track portion of the rail body wherein a cut out portion or window is provided. A series of ball bearings are confined within the endless raceway whereby the window exposes a portion of the ball bearings which are disposed in bearing relationship to the associated track portion of the rail, so as to minimize resistance therebetween.
