description An elongated cylindrical roller tube is rotatably supported between frame members by a pair of bearing units secured to opposite end portions of the tube. Each bearing unit includes a tubular shaft supporting a hexagonal stub axle for axial movement between an outwardly projecting position engaging a frame member and an inwardly retracted position against the bias of a spring member connected to the shaft. An anti-friction bearing is mounted on the tubular shaft and is retained within the roller tube by an annular adapter. An annular dust cover projects radially outwardly from the tubular shaft to protect the bearing. Some parts are molded of an electrically conductive plastics material, and each hexagonal stub axle has a slightly resilient outer surface, a rigid core pin and a tapered and twisted outer tip portion.
