Rotary chains were developed mainly for chain drive applications involving extremely heavy loads or particularly adverse operating conditions. Chains of this type are particularly resistant to violent shocks, wear and intense operating conditions, and have therefore enjoyed increasing success in a wide variety 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 built to the same design, heavy duty cranked link chains making it simpler to lengthen or shorten the chains when required. They have another advantage 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 metal or special tempered steel, according to the anticipated mechanical load. Chains put through extremely high loads are fitted with induction-hardened pins, making them not only extremely tough, but also giving them the highest possible level of surface hardness.
