Abstract: A combined bearing sealing and bearing adjusting subassembly for use with two members which rotate relative to each other upon a tapered roller bearing assembly, such as a belt conveyor idler roll which rotates relative to a stationary shaft upon a pair of axially spaced tapered roller bearing assemblies, and the combination of such a bearing sealing and bearing adjusting subassembly with a conveyor idler roll assembly. A separate cartridge-like subassembly is mounted between the two relatively rotatable members and contiguous each respective tapered roller bearing assembly. Each cartridge-like subassembly includes a combined contact seal and a labyrinth seal which cooperate to prevent ingress of foreign matter into the corresponding bearing assembly or the egress of lubricant from the bearing assembly.
