Bush chains are produced relative to ČSN 02 3301 and in space according to ČSN 02 3329. Our manufacturing program also includes non-standard bush chains produced according to your internal documentation.
A bush chain is very similar to the roller chain. However, it does not possess friction – reducing rollers and is bush chain china certainly thus ideal 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 frequently found 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.
