A linear motion bearing assembly comprising a ball retainer structure having at least a portion of a plurality of open axial ball tracks formed therein. The ball tracks include an open load bearing portion, an open return portion and turnarounds interconnecting the load bearing and return portions. A plurality of bearing balls are disposed in the ball tracks. A plurality of load bearing plates are axially positioned adjacent the ball retainer structure for receiving load from the balls disposed in the load bearing portion of the ball tracks. A bearing plate to housing intermediary load structure comprises a plurality of pieces and defines at least two spaces in between the pieces. The bearing plate to housing intermediary load structure extends circumferentially around the ball retaining structure. An inner arc of the pieces have a radius of curvature corresponding to a radius of curvature of the ball retainer structure. |
