heavy duty cranked link chains rotary chains were developed primarily for chain drive applications involving extremely large loads or particularly adverse operating conditions. Chains of the type are especially resistant to violent shocks, wear and severe operating conditions, and have consequently enjoyed increasing success 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 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 advantage over regular roller chains – all links are at the mercy of the same degree 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 steel, according to the expected mechanical load. Chains subjected to incredibly high loads are installed with induction-hardened pins, making them not only quite challenging, but also providing them with the highest possible degree of surface hardness.
