<p>A shaft assembly (10) includes an outer shaft (12) having a plurality of grooves (64-72) which extend between opposite end portions of the outer shaft. An inner shaft (14) has a plurality of projections (82-90) which extend between opposite end portions of the inner shaft. A plurality of bearing assemblies (22-30) cooperate with the grooves (64-72) in the outer shaft (12) and the projections (82-90) on the inner shaft (14) to support the inner and outer shafts for axial movement relative to each other. The bearing assemblies (22-30) include rotatable bearing members (42) which are disposed between longitudinally extending side surfaces of the grooves (64-72) in the outer shaft (12) and a longitudinally extending side surfaces of projections (82-90) on the inner shaft (14). The bearing members (42) are rotatably mounted in slots (108) disposed in retainer strips (100).</p> |
