1 Add 0.500 inches to the Pitch Diameter to get the Overall sprocket Diameter. Subtract 0.500 inches from
the Pitch Diameter to get the Flange Diameter.
2 Stock Bore Notations: NB = No Bore, CB = Core Bore, MPB = Minimum Plain Bore.
3 Larger bore sizes available.
4 Sprocket Number Notations: FL = Flangeless, LH = Large Hub, FLLH = Flangeless & Large Hub, MT = Machined Teeth,
HOT = High Temp Plastic.
