Abstract: A track assembly includes a guide rail secured to a piece of furniture, a runner secured to a drawer and formed with end stops that run against stationary stops to limit the movement of the runner, an inner slide rail interconnecting the runner and the guide rail to one another to effect a linear travel of the runner relative to the guide rail. Positioned between the slide rail and the runner and the guide rail are cages for retaining balls therein. Each cage is provided in its end zones with supplemental elastic stops which cooperate with end stops so that stationary stops are first impacted by the elastic stops to align possibly tilted drawers before being impacted by the end stops.
