Rotary chains were developed primarily for chain drive applications involving extremely large loads or particularly adverse operating conditions. Chains of this type are particularly resistant to heavy duty cranked link chains violent shocks, wear and intense operating conditions, and have as a result enjoyed increasing achievement in a wide variety of applications recently.
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 definitely that their links are built to the same pattern, making it simpler 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 expected mechanical load. Chains subjected to extremely high loads are fitted with induction-hardened pins, making them not only quite challenging, but also giving them the highest possible degree of surface hardness.
