The invention relates to the suspension of a door leaf of a sliding door in rail-bound means of mass transportation, such as underground railways, passenger train cars, means of local public transportation, and the like, by means of carrying rollers in a carrying rail arranged in the upper region of the door leaf or above the door leaf. The invention is characterized in that a steel insert having an at least substantially circular track is inserted into the carrying rail, that the carrying rollers are designed as steel rollers having a concave cross-sectional shape on the running surface, and that an adjustment roller is provided, which abuts the adjustment surface of the carrying rail opposite of the steel insert under preload.
