Bush chains are produced in accordance with ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing programme also includes non-standard bush chains produced in accordance to our internal documentation.
A bush chain is quite similar to the roller chain. However, it does not have friction – reducing rollers and is definitely thus suitable Speed Gear Reducer rather for lower driving speeds. The permitted standard motion speeds of the slow-running 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 operation in warm and humid environment where the use of belt drives will be inappropriate.
