What is iglidur®?

How does self-lubrication work?

Millions of the solid lubricants are embedded in tiny chambers in the solid, usually fibre-reinforced material. From these chambers, the material releases infinitesimal amounts of solid lubricants during movement. This is sufficient to satisfactorily lubricate the immediate surrounding area.

What's more, they help reduce the coefficient of friction of the iglidur materials. They are not indispensable for the bearings' function, but have a supporting effect. Since they are embedded in the tiny chambers, they cannot be forced out.

Thanks to self-lubrication, maintenance can be reduced to a minimum wherever iglidur materials are used. The incorporated solid lubricants make regular relubrication unnecessary, and dirt or dust cannot stick to the bearing.

Predictable service life

iglidur® materials have been tested thousands of times under realistic conditions and have proven their worth millions of times in many different applications. The data obtained from the tests flows into the free igus online tool, with which the service life can be exactly predicted, e.g. for plain bearings, bar stock and slewing ring bearings made of iglidur materials.

Wear test: how does iglidur perform compared to other plastics?

Test parameters:

• Rotation
• Speed v = 0.3m/s
• Load p = 1N/mm²
• Shaft material: V2A

The result shows that the different base polymers achieve very different lifetimes. iglidur® achieves a comparatively high value as a compound based on one of the base polymers also tested.
