Abstract
A linear motion bearing assembly (20) as provided for movement along a splined shaft (10). The rolling element retainer of the bearing assembly (20) is assembled from a plurality of arcuate interengageable self-contained rolling element retainer segments (22). Each of the rolling element retainer segments (22) includes at least one rolling element track (30) having a load bearing portion (34) and a return portion (36). At least one load bearing plate (44) is axially positioned in each segment and serves to receive and transmit loads from the bearing rolling elements (32) in the load bearing portion (34) of the ball tracks (30). An extended housing retainer structure encloses all of the exposed exterior surfaces of the rolling element retainer segments (22) and is configured and dimensioned to maintain the rolling element retainer segments (22) in position and to receive a load either directly or indirectly from the load bearing plates (44).
