Bush chains are manufactured relative to ČSN 02 3301 and in space bush chain china according to ČSN 02 3329. Our manufacturing programme also includes nonstandard bush chains produced according to your internal documentation.
A bush chain is very like the roller chain. Nevertheless, it does not possess friction – reducing rollers and is usually thus appropriate rather for lower generating speeds. 
The permitted regular motion speeds of the slow-running bush chains range from 0.3 m/sec to 1 1.2 m/sec, with a maximum of 3.0 m/sec. Bush chains are most regularly found in applications requiring continuous operation under coarse working circumstances as well as operation in warm and humid environment where the use of belt drives would be inappropriate.
