Bush chains are produced relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing program also includes non-standard bush chains produced in bush chain china accordance to our internal documentation.
A bush chain is 
very like the roller chain. Nevertheless, it does not possess friction – reducing rollers and is usually thus suitable rather for lower driving speeds. The permitted standard movement speeds of the slow-running bush chains range between 0.3 m/sec to 1 1.2 m/sec, with no more than 3.0 m/sec. Bush chains are most frequently found in applications requiring continuous operation under coarse working conditions as well as operation in warm and humid environment where the utilization of belt drives would be inappropriate.
