A slide bearing carrier locator includes a bearing carrier having rollers disposed between a carrying rail and a sliding rail, a support holder provided at the front end of the carrying rail for the sliding rail to hold against the support holder to slide, and a retaining surface provided on the carrying rail. A stopper unit is provided on the bearing carrier. The stopper unit comprises a locating portion and a release portion. The locating portion has a stopper end in relation to the retaining surface of the carrying rail to prevent the bearing carrier from moving backward. The release portion has a protrusion in relation to a side panel of the bearing carrier. When the sliding rail is inserted relatively to the carrying rail, the sliding rail compresses the protrusion for the bearing carrier to move backwards.
