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 intense operating conditions, and also have consequently enjoyed increasing heavy duty cranked link chains success in a wide selection of applications recently.
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 all built to the same design, making it simpler to lengthen or shorten the chains when needed. They have another advantage over standard roller chains – all links are subject to 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 steel or special tempered metal, according to the expected mechanical load. Chains put through 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.
