Factsheet - Gas nitrocarburising
How well does gas nitrocarburising protect shafts against corrosion? In the test, various shaft materials in combination with iglidur® plain bearings and igutex® fibre composite plain bearings were subjected to a salt spray test. All test results can be found in the factsheet.

Factsheet - avoid reduced interference fit
The use of anti-corrosion agents can reduce the interference fit of your plain bearings. We have therefore tested various anti-corrosion agents. You can find out which agents almost double the interference fit in this factsheet.

Factsheet - locating spigot for sleeve bearing
You have various options for locating spigots for sleeve bearings. In this factsheet, you can find out what these are and what you need to bear in mind when securing them.

Factsheet - Sealing concepts with felt
Find out why felt is suitable for sealing bearing points. This factsheet also contains important design information on plain bearings with felt seal.

Factsheet - Mounting igutex® plain bearings

Here you can find out everything you need to know about mounting our igutex® fibre composite plain bearings.
