Bush chains are manufactured relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing programme also includes nonstandard bush chains produced according to your internal documentation.
A bush chain is quite like 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-working bush chains range between 0.3 m/sec to at least one 1.2 m/sec, with a maximum of 3.0 m/sec. Bush chains are most regularly found in applications requiring continuous procedure under coarse working conditions as well as operation in warm and humid Roots Vacuum Pumps environment where the use of belt drives would be inappropriate.
