Open the CIPO recordAbstract From the Canadian patent
A unique ball-bearing retainer is disclosed for use with two or three part drawer slides for filing cabinets and the like. The retainer uses a standard channel member with upturned side flanges. The flanges are equipped with round apertures and then bent at the approximate mid-point thereby creating an elliptical aperture providing a seat for rotation of a common steel ball. The ball comes in contact with the aperture at the base and the top of the same such that during operation of the drawer slide the portions of the ball having maximum rotation or movement do not contact the retainer thereby reducing friction, and increasing the life of the drawer slide.
