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. For sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.5. Models with approximate masses in bold typeface have one punched hole for lifting.MaterialMaterial2C typedDHMaterialWelded construction: machine-structuralcarbon steel (teeth) and structural rolled steel (hub)Welded construction:structural rolled steel (teeth and hub)DPDOPilot BoreDiameterd1A typedDP1A typeMaterialMachine-structural carbon steelDONumber ofTeethBefore 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 number40
