Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. The outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. 1B-type sprockets marked with an * have an outer groove around the hub. Groove outer diameter is 27 for 9T, 37 for 11T, 42 for 12T and 47 for 13T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.6.
