Rotary chains were developed primarily for chain drive applications involving extremely weighty loads or particularly adverse operating conditions. Chains of the type are especially resistant to violent shocks, wear and extreme operating conditions, and have as a result enjoyed increasing achievement in an array of applications in heavy duty cranked link chains 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 usually that their links are built to the same design, making it easier to lengthen or shorten the chains when required. They have another advantage 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 can be found 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, making them not only quite challenging, but also giving them the highest possible degree of surface hardness.
