Claim:
A pull-out mechanism for mounting a drawer in a drawer cavity comprising: an upper rail having a substantially U-shaped cross-section, said upper rail being aligned with the drawer, and an intermediate rail which is positioned below the upper rail, wherein a bearing holder is disposed between a first end of the intermediate rail and the upper rail, wherein in a cross section perpendicular to the longitudinal axis of the upper rail a single bearing ball is mounted on the bearing holder providing a first horizontal and vertical load support of the pull out mechanism on a first side of a vertical center plane of the intermediate rail, and wherein two rollers or wheels are mounted on the bearing holder such that the axes of rotation of the two rollers or wheels are perpendicular to each other providing a cooperating second horizontal and vertical load support of the pull out mechanism on a second opposing side of the vertical center plane of the intermediate rail, and wherein a substantially horizontal auxiliary roller is mounted on the bearing holder such that it bears against the first end of the intermediate rail and is disposed between the intermediate rail and the upper rail providing horizontal load support of the pull out mechanism.
