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