Rotary chains were developed primarily for chain drive applications involving extremely weighty loads or heavy duty cranked link chains particularly adverse operating conditions. Chains of this type are particularly resistant to violent shocks, wear and intense operating conditions, and also have therefore 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 advantage of rotary chains is certainly that their links are built to the same pattern, making it simpler to lengthen or shorten the chains when necessary. They have another benefit 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 steel or special tempered metal, according to the expected 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 level of surface hardness.
