Rotary chains were developed primarily for chain drive applications involving extremely large loads or particularly adverse operating conditions. Chains of the type are particularly resistant to violent shocks, wear and severe operating conditions, and also have consequently enjoyed increasing achievement in a wide selection of applications in recent years.
For the most part, rotary chain heavy duty cranked link chains dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant benefit of rotary chains is that their links are built to the same pattern, making it easier to lengthen or shorten the chains when needed. They have another advantage over standard roller chains – all links are subject to the same level of wear.
ELITE rotary chains with cranked links are fitted with cotter pins. The chain plates can be found in naturally hardened steel or special tempered metal, according to the expected mechanical load. Chains put through extremely high loads are installed with induction-hardened pins, making them not only extremely tough, but also giving them the highest possible level of surface hardness.
