Abstract
A sliding door assembly includes a sliding door that is slidingly mounted to a top track via one or more top guide assemblies. The sliding door is also slidingly mounted to a bottom track. Each top guide assembly includes a top guide wheel that rotationally mounts to the top guide assembly and engages the top track to guide the sliding door. The guide wheel rotates relative to the top guide assembly about an axis that extends horizontally in a direction perpendicular to a direction of travel of the sliding door. The guide wheel also movably mounts to the top guide assembly so that the guide wheel moves upwardly and downwardly relative to the top guide assembly and sliding door to correct for any variation in the gap between the top and bottom tracks.
