Bush chains are produced relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing programme also includes non-standard bush chains produced in Energy-conserving Vacuum Pump accordance to our internal documentation.
A bush chain is quite similar to the roller chain. Nevertheless, it does not have friction – reducing rollers and is usually thus appropriate rather for lower generating speeds. The permitted regular movement speeds of the slow-running 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 used in applications requiring continuous operation under coarse working conditions as well as procedure in warm and humid environment where the use of belt drives would be inappropriate.
