Kässbohrer Geländefahrzeug AG

In the chassis of its tracked vehicles, Kässbohrer Geländefahrzeug AG uses igutex® fibre composite bearings that function reliably even in dirt.

Demarko

Demarko uses igutex® fibre composite bearings in oscillating axles for semi-trailers. The bearings are part of the igus® standard range and require no additional lubrication.

Ship & Yacht Engineering Ltd.

The Ship & Yacht Engineering Ltd. stern gallows is suitable for a swivel load of up to 20 tons and uses igutex plain bearings in the swivel kinematics because they also work in weather and salt water.

Thaler GmbH & Co. KG

iglidur plain bearings can also be found in Thaler GmbH & Co. KG farm loaders, where they are used because the bearing points are resistant to dirt and require little maintenance.
