Abstract
A linear motion bearing assembly is provided having a rail assembly comprising a base member and a pair of vertical arms which have flexible characteristics with respect to the base member. A bearing carriage assembly is also included which has a bearing carriage and a pair of legs extending therefrom. The extending legs define a longitudinal channel for accommodating the rail assembly, and are flexible with respect to the bearing carriage. A plurality of load bearing race inserts are positioned on the vertical arms of the rail assembly and the extending legs of the bearing carriage assembly. A load bearing surface of the plurality of load bearing inserts has a predisposed compressive stress. A plurality of rolling elements are disposed in load bearing tracks which are defined by the plurality of load bearing race inserts.
