Abstract: This invention provides an idler for use in conveyor systems and associated shaft and support structure that reduces the potential for infiltration of contaminants into the bearing assemblies at the opposing ends of the shaft. By use of stampings, co-molded polymer with sealed metal end caps, press-fit end shafts and stamped-metal support structures a more contamination-resistant and efficiently constructed idler assembly is provided. A hollow shaft center section can be used. The polymer defines at least three sealing structures. The shaft defines a multi-piece unit, with the end shafts press-fit onto the center shaft section and held in place by the bearing subassemblies—affixed to the idler sleeve. The support framework includes three stamped and/or cut, and folded sheet metal pieces—a center section with a pair of opposing central risers that engage end shafts, and two opposing, separately attached, end risers, that engage outermost idler end shafts.

Abstract: A hybrid drive component, such as a pulley, a drive sprocket, or an idler is composed of metal and composite material. The drive component manufacturing methods extend the overall life of the pulley while also reducing material usage and product weight thereby making the application more efficient. The drive component includes a drive element, a hub/bearing element and a connecting element. The connecting element is a molded construction that interconnects the drive element and the hub element.
