What is iglidur®?
iglidur materials are developed by igus, made of high-performance polymers that are characterised by their special properties: Their special composition makes them extremely wear-resistant, robust and self-lubricating. Their service life can be precisely determined. In addition, each iglidur material has individual specifications and strengths that make it suitable for special applications.
What are iglidur materials made of?
All iglidur materials are made up of three components: base polymers, fibres and fillers, solid lubricants. As it is not possible for one universal material to fulfil all tasks equally well, there are different iglidur materials. Each has a different proportion of the three components and a different application area.
How does self-lubrication work?
Base polymer with fibres and solid lubricants, magnified 200 times, dyed
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.
They also help to reduce the coefficient of friction of iglidur materials. They are not indispensable for proper function of the bearing, but provide support. As they are embedded in the tiny chambers, they cannot be pressed out.
Thanks to the self-lubricating effect, maintenance on iglidur materials can be reduced to a minimum. Regular relubrication is not necessary due to the solid lubricants and dirt or dust cannot settle.
Predictable service life
iglidur® materials have been tested thousands of times in practical trials and proven millions of times in application. The test data from the trials flow into the free igus online tool, with which the service life for e.g. plain bearings, bar stock and slewing ring bearings made of iglidur materials can be precisely predicted.

Wear test: how does iglidur perform compared to other plastics?
Test parameters:
- Rotation
- Speed v = 0.3m/s
- Load p = 1N/mm²
- Shaft material: 304 SS
Test results show that various base polymers exhibit very different service lives. iglidur achieves a comparatively high value as a compound based on one of the base polymers tested.
