Bolt Norge AS, a Norwegian company : the beginning | the developement | now

the beginning.. in the end of the 1980's two grown up boys decided to find a solution to the problems with ovality in digging machines. They had experienced that play in bolt-connections was both expensive and caused valuable time doing the repair works. The Bondura was developed and tested in various construction machinery with both success and failure.		Trying to produce a bolt which did not need any lubrication, there was a lot of experience gained. They tried out various steel as well as bearings, and after working close to the actual users Bolt Norge finally ended up with the Bondura as you know it today.
