Abstract
A slide rail device includes a guide rail, a slider slidable along the guide rail, and a pair of cylindrical roller train sets disposed at two opposite sides of the guide rail. Each cylindrical roller train set is disposed between the guide rail and the slider, and has a plurality of cylindrical rollers. Each cylindrical roller has a first roller surface portion and a second roller surface portion that is recessed relative to the first roller surface portion. The first roller surface portions of the cylindrical rollers are in rolling contact with the guide rail and the slider, and the second roller surface portions of the cylindrical rollers are free of contact with the guide rail and the slider.
