Rotary chains were developed primarily for chain drive applications involving extremely heavy loads or particularly adverse operating conditions. Chains of the type are especially resistant to violent shocks, wear and intense operating conditions, and also have as a result enjoyed increasing achievement 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 easier to lengthen or shorten the chains when necessary. They have another advantage over regular 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 heavy duty cranked link chains hardened steel or special tempered metal, according to the anticipated mechanical load. Chains put through incredibly high loads are fitted with induction-hardened pins, producing them not only quite challenging, but also giving them the highest possible degree of surface hardness.
