Suspension for a sliding drawer having a channel-section outer rail, a channel-section intermediate rail nested within the channel of the outer rail and sliding on a linear bearing, and an inner channel-section rail nested within the channel of the intermediate rail and sliding relative to it on a linear bearing. A flexible latch latches the inner rail to the intermediate rail during initial opening movement of the suspension so that the nested inner and intermediate rails reinforce one another and provide a stronger support. The latching also synchronizes the movements of the rails on opposite sides of the drawer and reduces problems associated with displacements of the bearings on opposite sides of the drawer.

A sliding drawer suspension comprising an outer channel-section rail including channel sides and a channel bottom, and having in a retracted position an intermediate channel rail nested between the sides of the channel of the outer channel section rail, said intermediate rail having channel sides and a channel bottom, and an inner channel-section rail nested in a retracted position between the intermediate channel sides, outer and inner linear ball bearings each including a ball cage between the outer and intermediate rails and between the intermediate and inner rails, respectively, permitting the intermediate and inner rails to slide forwardly relative to the outer and intermediate rails, respectively, to an extended position, latching means releasably latching the inner rail in stationary nested relationship within the intermediate rail, whereby when the inner rail is extended, the intermediate rail remains stationary relative thereto and moves together therewith relative to the outer rail in stationary latched connection thereto, a pair of stop members on the outer and intermediate rails arranged for engaging end surfaces on the outer ball cage to limit extension of the intermediate rail relative to the outer rail, a pair of stop members on the intermediate and inner rails arranged for engaging end surfaces on the inner bearing ball cage to limit extension of the inner rail relative to the intermediate rail, said bearing members being normally positioned so that the end surfaces of each ball cage are spaced at equal distances from the stop surfaces with which they engage, and including on at least one rail selected from said outer rail and said intermediate rail an abutment member which in the closed position of the suspension abuts an end surface of the outer bearing ball cage and engages it when displaced from its normal position and shifts it to its normal position on closing movement of the suspension.
