An improved return roller assembly for use in a continuous belt conveyor system comprises a shaft disposed between a pair of sealed bearing assemblies that are mounted to the underside of a frame member to define the return flight section of the conveyor system so as to support and guide the conveyor belt. The ends of the shaft, which is preferably made out of cold-rolled steel, connect to bearings that are rotatably disposed in the bearing housing. Preferably, the bearing assemblies have a sealed bearing to reduce the likelihood of clogging or other damage from dust, bulk material or other debris that may be present and, therefore, reduce the cost and downtime associated with maintenance and repair.
