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 extreme operating conditions, and have as a result enjoyed increasing achievement in an array of applications in recent years.
For the most part, 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 simpler to lengthen or shorten the chains when required. They have heavy duty cranked link chains another advantage over standard 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 metal, according to the anticipated mechanical load. Chains subjected to incredibly high loads are fitted with induction-hardened pins, producing them not only extremely tough, but also providing them with the highest possible degree of surface hardness.
