Bush PTO Drive Shaft chains are produced in accordance with ČSN 02 3301 and in dimensions according to ČSN 02 3329. Our manufacturing program also includes non-standard bush chains produced according to your internal documentation.
A bush chain is quite like 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-operating 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 conditions as well as operation in warm and humid environment where the use of belt drives would be inappropriate.
