Bush chains are produced in accordance with ČSN 02 3301 and in space 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. However, it does not possess friction – reducing rollers and is certainly thus suitable rather for lower bush chain china driving speeds. The permitted standard motion speeds of the slow-operating 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 used in applications requiring constant operation under coarse working circumstances as well as procedure in warm and humid environment where the use of belt drives would be inappropriate.
