Abstract: A rolling element chain (10) comprises a plurality of rolling elements (14) arranged in close succession and a longitudinal supporting band (12). The supporting band (12) in turn comprises a plurality of recesses (16) for the accommodation of the rolling elements (14), a plurality of retaining elements (20) for retaining the rolling elements accommodated in the recesses (16), where each rolling element (14) is assigned at least one retaining element (20), and at least one longitudinal flexible element (18) for interconnection of the retaining elements (20). Each rolling element (14) is retained, by the at least one retaining element (20) assigned to it, in the longitudinal direction (L) of the supporting band (12) either at its leading side only or at its following side only.

Abstract: A chain of rolling elements comprises a plurality of rolling elements and an elongate carrier belt with a plurality of recesses for receiving the rolling elements, a plurality of retainers for retaining the rolling elements received in the recesses and at least one elongate flexible element for connecting the retainers. The carrier belt comprises two lateral edge portions and a central portion connecting them, the retainers being connected to the at least one flexible element in the lateral edge regions of the carrier belt. Separate retainers are associated with successive rolling elements, at least one retainer associated with each rolling element being provided on the at least one flexible element in the longitudinal direction thereof before and after each rolling element.

Abstract: In a screw drive, in particular a ball screw drive, a double nut, formed of a pair of individual nuts, is tightened on a threaded spindle and the individual nuts are secured together against relative rotation by a locking member. The locking member is secured within a radially extending recess formed in and bridging the individual nuts. The locking member can be inserted with a certain amount of play into the recess or borehole and then secured within the recess by a cement or similar material so that it cannot be displaced. Various types of locking members can be used, such as locking bolts or threaded bolts. When the locking member is connected into the recess or ball it prevents any rotation of the individual nuts relative to one another.
