The heavy duty roller chain is manufactured with thicker inner and outer link plates. This improves the chains working load and fatigue resistance while enduring more frequent & heavier shock loads. Heavy series chain is a great option for mechanical engineers designing drives that require more strength, but restricted to tight space requirements. These chains are readily available in single strand, double strand and triple strand options. We offer two styles, which is your standard riveted and cottered construction.
Typically Nitro heavy series roller chains is best suited for drives that have moderate loads, frequent starting/stopping or forward/reverse directional changes. Below are just a some examples of common everyday uses for our heavy series chain.
First off, both chains are recognized as ANSI B29.1 industry size roller chains. The dimensions are very similar except heavy duty chains do have thicker plates, which makes the chain wider. With heavy duty roller chain you gain both working load strength and greater fatigue resistance. Standard chains are better for smoother operations with lighter loads, whereas heavy duty can handle heavier loads and more repetitive shock loads.
