Rotary chains were developed mainly for chain drive applications involving extremely heavy loads or particularly adverse operating conditions. Chains of the type are especially resistant to violent shocks, wear and severe operating 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 pattern, making it easier to lengthen or shorten the chains when necessary. They have another advantage 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 are available in naturally hardened steel or special tempered steel, according to the anticipated mechanical load. Chains put through extremely high loads are fitted with induction-hardened pins, producing them not only quite challenging, but also providing them with the heavy duty cranked link chains highest possible degree of surface hardness.
