Bush chains are produced relative to ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing program also Helical Gearboxes includes non-standard bush chains produced in accordance to our internal documentation.

A bush chain is very similar to the roller chain. However, it does not have friction – reducing rollers and is definitely thus appropriate rather for lower generating speeds. The permitted standard motion 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 frequently found in applications requiring constant procedure under coarse working conditions as well as operation in warm and humid environment where the utilization of belt drives will be inappropriate.
