Rotary chains were developed primarily 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 extreme operating conditions, and have therefore enjoyed increasing achievement in a wide range 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 heavy duty cranked link chains definitely that their links are all constructed to the same pattern, making it easier to lengthen or shorten the chains when needed. They have another benefit over standard roller chains – all links are subject to the same degree of wear.
ELITE rotary chains with cranked links are fitted with cotter pins. The chain plates are available in naturally hardened metal or special tempered steel, 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 providing them with the highest possible degree of surface hardness.
