Bush chains are manufactured relative to ČSN 02 3301 and in space bush chain china according to ČSN 02 3329. Our manufacturing program also includes nonstandard bush chains produced according to our internal documentation.
A bush chain is quite like the roller chain. Nevertheless, it does not possess friction – reducing rollers and is definitely thus appropriate 
rather for lower driving speeds. The permitted standard movement speeds of the slow-working 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 frequently found in applications requiring continuous procedure under coarse working conditions as well as operation in warm and humid environment where the use of belt drives will be inappropriate.
