Bush chains are 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 quite like the roller chain. Nevertheless, it does not possess friction – reducing rollers and is certainly thus suitable rather for lower Gas-cooling Vacuum Pump traveling speeds. The permitted regular motion 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 used in applications requiring constant procedure under coarse working conditions as well as operation in warm and humid environment where the usage of belt drives will be inappropriate.
