Rotary chains were developed primarily for chain drive applications involving extremely weighty loads or particularly adverse operating conditions. Chains of this 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 dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant benefit of rotary chains is certainly that their links are all constructed to the same design, making it easier to lengthen or shorten the chains when needed. They have another benefit over standard roller chains – all links are at the mercy of 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 anticipated mechanical load. Chains put heavy duty cranked link chains through extremely high loads are installed with induction-hardened pins, making them not only quite challenging, but also giving them the highest possible level of surface hardness.
