Rotary chains were developed mainly for chain drive heavy duty cranked link chains applications involving extremely weighty loads or particularly adverse operating conditions. Chains of the type are especially resistant to violent shocks, wear and severe operating conditions, and also have therefore enjoyed increasing success in an array of applications recently.
Generally, rotary chain dimensions are standardized under ISO 3512, ANSI B 29.10 and DIN 8182. One significant benefit of rotary chains is certainly that their links are all constructed to the same design, 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 level 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 metal, according to the anticipated mechanical load. Chains put through extremely high loads are fitted with induction-hardened pins, producing them not only quite challenging, but also giving them the highest possible level of surface hardness.
