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. 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 44 for 9T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.6. Models with approximate masses in bold typeface have one punched hole for lifting.7.
