Bush chains are Scroll Air Compressors manufactured relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing program also includes nonstandard bush chains produced in accordance to your internal documentation.
A bush chain is very similar to the roller chain. However, it does not have friction – reducing rollers and is usually thus suitable rather for lower traveling speeds. The permitted regular 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 found in applications requiring constant procedure under coarse working conditions as well as procedure in warm and humid environment where the use 
of belt drives would be inappropriate.
