Abstract of the Disclosure A drawer slide assembly for supporting a drawer to slide open and closed in an opening in a cabinet frame includes an elongated upper member extending longitudinally of the drawer and secured to the latter and a parallel lower member spaced below the upper member and secured to the frame. A pair of rollers are journaled side by side on the upper member near the rear thereof and engage track sections formed on the lower member. Similarly, a second pair of rollers are journaled on the lower member near the front thereof and engage track sections formed on the upper member. The rollers are given a short axial profile while having effective diameters greater than their actual diameters by forming the rollers with surfaces which are inclined at acute angles relative to the roller axes and the associated track sections are inclined at similar angles. Each of the second pair of rollers is journaled by a plurality of bearing balls which are arranged so that the line of force of the load of the drawer is offset from the centers of the balls in a direction to produce a force couple which results in all of the balls supporting a portion of the load.
