Abstract

A linear ball bush comprises a cage having a cage axis and a plurality of ball circuits, at least one ball circuit comprising two straight ball rows substantially parallel to the cage axis and two curved ball rows connecting the two straight ball rows, and a plurality of runner plates which each provide for the guidance of the ball circuit. The runner plates comprise straight track sections continued with substantially constant profile over their entire length, and between these a middle rib which is continued to each of the runner plate ends with substantially constant profile. The curved track sections connect the straight track sections and pass transversely through the middle rib.
