vasteketjua
Vasteketjua is a Finnish technical term used to describe a chain that is designed to be rigid or to maintain fixed spacing between its links. In practice, the concept refers to a chain system with limited articulation, used in mechanisms where flexible movement would compromise alignment or stability. Vasteketjua can be employed in guiding and bracing applications, or as a structural connector within machinery, where a conventional flexible chain would permit undesired motion.
The word is a compound of vaste, meaning rigid or fixed, and ketju, meaning chain. The form
In engineering usage, vas teketjua is distinguished from ordinary, flexible chain systems such as roller chains
