Bush chains are manufactured relative to ČSN 02 3301 and in dimensions bush chain china according to ČSN 02 3329. Our manufacturing program also includes non-standard bush chains produced according to our internal documentation.
A bush chain is very 
like the roller chain. However, it does not possess friction – reducing rollers and is definitely thus appropriate rather for lower driving speeds. The permitted regular movement speeds of the slow-running bush chains range between 0.3 m/sec to at least one 1.2 m/sec, with a maximum of 3.0 m/sec. Bush chains are most frequently used in applications requiring constant operation under coarse working circumstances as well as operation in warm and humid environment where the use of belt drives would be inappropriate.
