Bush chains are produced relative to ČSN 02 3301 and in dimensions bush chain china according to ČSN 02 3329. Our manufacturing programme also includes nonstandard bush chains produced in accordance to our internal documentation.
A bush chain is very like the roller chain. However, it does not have friction – reducing rollers and can be thus appropriate rather for lower generating speeds. The permitted regular movement speeds of the slow-operating bush chains range between 0.3 m/sec to at least one 1.2 m/sec, with no more than 3.0 m/sec. Bush chains are most regularly used in applications requiring constant operation under coarse working conditions as well as procedure in warm and humid environment where the use of belt drives would be inappropriate.
