| 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 coil spring confined within 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 snap-fits onto the outer end portion of the tubular shaft for protecting the bearing, and the stub axle is retained within the shaft by detents which permit pulling the stub axle from the shaft for axle replacement. The axle, shaft, adapter and cover are each molded of an electrically conductive plastics material, and each hexagonal stub axle has a resilient outer, surface and a tapered and twisted outer tip portion extending from a slightly tapered portion for self-alignment of the axles with mating hexagonal holes within the frame members. |
