Abstract
Each embodiment has a linear bearing member having a ball retainer captured in the member to retain the ball bearings when the opposing bearing member is removed from the assembly. In one embodiment the opposing member has a race resting on the balls. In the other embodiment the first member has upper and lower races and the retainer holds ball bearings against each while the opposing bearing member fits between the upper and lower balls and has upper and lower races cooperating with the balls so the opposing member can be loaded upwardly or downwardly and still run on balls.
