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 intense operating heavy duty cranked link chains conditions, and have therefore enjoyed increasing achievement in an array of applications recently.
Generally, rotary chain dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant benefit of rotary chains is usually that their links are constructed to the same design, making it easier to lengthen or shorten the chains when needed. They have another benefit over regular 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 through extremely high loads are installed with induction-hardened pins, producing them not only quite challenging, but also giving them the highest possible degree of surface hardness.
