Abstract
A linear bearing assembly is provided including a housing for receiving a plurality of axial ball retainers and bearing plates therein. The housing includes a pair of end caps disposed in both longitudinal ends of the bearing assembly with the end caps having a plurality of angled ball turnarounds formed therein. The bearing plates and axial ball retainers form portions of a plurality of ball tracks with the bearing plates having grooves formed in an inner radial surface thereof for defining a top radial portion of the load bearing paths and circumference grooves defining side walls of the return paths. The bearing plates and axial ball retainers are arranged so as to allow optimization of ball track quantities to radial height of the overall bearing assembly and thus increase ball track quantities and load/life characteristics of the bearing assembly.
