Abstract
A roller assembly is provided as an easily replaceable assembly for use with a sliding door. The roller assembly includes a roller or wheel mounted in a roller housing and carried in a cantilevered manner at one end of a leaf spring. The opposite end of the leaf spring is permanently bent to form a hook which is engageable with a mounting tab on an upper or lower door edge through a mounting insertion gap in the door edge such that the leaf spring extends across a bearing tab. When the hook is engaged on the mounting tab the roller is carried in a roller receiving pocket in the door edge such that the leaf spring bears against a bearing tab. The leaf spring allows the roller to move into and out of a roller receiving pocket to accommodate imperfections and obstructions in a stationary track on the door frame in which the roller travels.
