Bush chains are produced relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing program also includes non-standard bush chains produced in accordance to our Reciprocating Vacuum Pumps internal documentation.

A bush chain is very similar to the roller chain. However, it does not possess friction – reducing rollers and is certainly thus suitable rather for lower driving speeds. The permitted standard motion speeds of the slow-working bush chains range from 0.3 m/sec to 1 1.2 m/sec, with no more than 3.0 m/sec. Bush chains are most frequently 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 will be inappropriate.
