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 21 for 9T, 25 for 10T, 30 for 11T and 32 for 12T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.MaterialWelded specification: machine-structuralcarbon steel (teeth) and structural rolled steel (hub)MaterialPrecut specification: machine-structural carbon steelWelded specification: machine-structuralcarbon steel (teeth) and structural rolled steel (hub)MaterialWelded specification: structural rolled steelPilot BoreDiameterdMaterialMachine-structural carbon steelNumber ofTeeth2021Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingSprocket NumberNumber of teethTypeChain number30
