Plastic Sprocket TypesThe standard styles of a plastic roller chain sprocket are A-plate style meaning that there is no hub on either side of the sprocket, B-hub style which has a hub on one side, and C-hub style which has a hub on two sides.
Standard bore styles for plastic sprockets are a stock bore, which is a plain unfinished hole in the center of the sprockets.
