Bush Rotary Air Compressors chains are manufactured in accordance with ČSN 02 3301 and in space according to ČSN 02 3329. Our manufacturing programme also includes nonstandard bush chains produced according to our internal documentation.
A bush chain is very like the roller chain. However, it does not have friction – reducing rollers and is definitely thus appropriate rather for lower driving speeds. The permitted standard movement speeds of the slow-working bush chains range from 0.3 m/sec to at least one 1.2 
m/sec, with a maximum of 3.0 m/sec. Bush chains are most frequently found in applications requiring continuous procedure under coarse working conditions as well as procedure in warm and humid environment where the use of belt drives would be inappropriate.
