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 according to our internal documentation.
A bush chain is quite similar to the roller chain. Nevertheless, it does not possess friction – reducing rollers and is definitely thus appropriate rather for lower generating speeds. The permitted regular motion speeds of the slow-working bush chains range from 0.3 m/sec to 1 1.2 m/sec, with a Sprial Reducers maximum of 3.0 m/sec. Bush chains are most regularly found in applications requiring constant procedure under coarse working circumstances as well as operation in warm and humid environment where the use of belt drives will be inappropriate.
