Bush chains are produced relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing program also includes nonOil less Air Compressors standard bush chains produced according to your internal documentation.
A bush chain is very like the roller chain. However, it does not have friction – reducing rollers and is thus suitable rather for lower generating speeds. The permitted standard movement speeds of the slow-operating bush chains range from 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 found in applications requiring continuous operation under coarse working circumstances as well 
as procedure in warm and humid environment where the use of belt drives would be inappropriate.
