60H heavy roller chain is manufactured with the exact dimensional specifications as a regular 60 chain, except for the side plates. 60H chain has a side plate thickness of 0.125" versus the standard of 0.093". The additional 0.032" of material thickness on each sidebar gives the chain a notation of being heavy-duty, hence where the "H" comes from in the 60H chain part number. The addition of material provides the chain with a higher load capacity of 1,099 LBS regarding tensile strength; this also improves the chain's capabilities for shock-load and torque-demanding applications. Our 60H heavy roller chain is manufactured per ANSI B29.1 dimensional specifications, meaning it will directly interchange with other brands.
