Rotary chains were developed mainly for chain drive applications heavy duty cranked link chains 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 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 can be that their links are built to the same design, making it simpler to lengthen or shorten the chains when required. They have another benefit 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 metal or special tempered steel, according to the anticipated mechanical load. Chains subjected to extremely high loads are installed with induction-hardened pins, producing them not only extremely tough, but also providing them with the highest possible degree of surface hardness.
