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 ). |
