  "abstract": "A sprocket for guiding or driving a conveyor chain of a carwash conveyor includes a sprocket ring and first and second support rings flanking opposite sides of the sprocket ring. Flanges on the first and second support rings are spaced apart axially from the sprocket ring so as to form a channel between the flanges that receives drive links of the conveyor chain. The first and second support rings and flanges thereof support a portion of a roller assembly of the carwash conveyor to thereby limit lateral tilting of the roller assembly and/or twisting of the conveyor chain. Also disclosed is a reversible roller assembly including a double-nosed lug, which can be reversed relative to the conveyor chain to extend the service life of the roller assembly.",
