<p>The spacer (18) is arranged between two adjacent rolling elements of an upper row of rolling elements and another two adjacent rolling elements of a lower row of rolling elements. The rolling elements are supported at a rail guide, and are longitudinally movable. The lower row of rolling elements is covered by an additional cover, where the rolling elements are formed as balls. A section of a chain (21) connects the distance spacer with the upper and lower rows of rolling elements. An independent claim is also included for a profiled rail guide with a spacer for rolling elements.</p> |
