Bush chains are manufactured relative to ČSN 02 3301 and in space according to ČSN 02 3329. Our manufacturing program also includes non-standard bush chains produced in accordance to your internal documentation.
A bush chain is quite similar to the roller chain. However, it does not have friction – reducing rollers and is certainly thus Gear rack appropriate rather for lower traveling speeds. The permitted standard motion speeds of the slow-working bush chains range between 0.3 m/sec to 1 1.2 m/sec, 
with a maximum of 3.0 m/sec. Bush chains are most regularly found in applications requiring constant operation under coarse working circumstances as well as procedure in warm and humid environment where the usage of belt drives will be inappropriate.
