Open the CIPO recordAbstract From the Canadian patent
A unique moulded roller bearing cage assembly for use for drawers and cabinets replaces standard metallic bearing cages and balls. The bearing cage, its rollers detachably fixed within the apertures, is loaded between the flanges of the channels on the standard two or three part drawer slide. The rollers before and during assembly are fixed at their ends integrally with the cage to allow for easy installation. Once the rollers come in contact with the raceways of the installation the detachable links are broken allowing the rollers to be free to rotate. The rollers and cages can be moulded in any configuration to allow for different channel and raceway shapes.
