Abstract
A rolling element guide for drawer guides consists of a furniture unit body rail mounted on the furniture unit body side wall and a drawer rail mounted on the drawer, rolling surfaces for the rolling elements transmitting the drawer load being arranged on both rails, the rolling elements being held in a roller cage arranged between the rails. For minimizing the rolling noise and for reducing the manufacturing costs, the rolling elements have pins on opposing end faces, these pins pivoting in the roller cage, the pins of rolling elements arranged in the same plane being staggered 90 degrees with respect to each other, which forms rolling surfaces on the rolling elements that are staggered 90 degrees with respect to each other, and high drawer loads can be transmitted.
