Abstract: A roller insert for a conveyor roller tube includes a cartridge housing having an inside end and an outside end, an outside bearing positioned proximate to the outside end of the cartridge housing, where the outside bearing has an inner race and an outer race, and a stub axle. The stub axle includes an elongate body portion having a drive interface portion positioned distally from the outside end of the cartridge housing. The roller insert also includes a bushing coupled to the inner race of the outside bearing, where the bushing includes a bore portion extending along the inner race of the outside bearing. The roller insert further includes a jacket at least partially surrounding an outer perimeter of the cartridge housing and extending in an axial direction to at least partially encapsulate the outer race of the outside bearing in the axial direction.
