The new iglidur® G1 material was subjected to various tests in the igus® test laboratory:
wear tests in the low and medium-load range in pivoting and rotating applications, surface pressure tests at high temperatures and moisture-absorption tests.

Load: 2 MPa / 45 MPa
Speed: 0.01 m/s
Shaft: aluminium, Cf53 and high grade steel
Bearing materials: iglidur® G, iglidur® G1 and metal/PTFE
The tested bearings made of the new iglidur® G1 material displayed significantly better wear properties. The coefficient of wear in the low-load range of 2 MPa was up to 75% below the wear of iglidur® G and therefore considerably below that of the tested bearings of competitors made of a metal/PTFE compound. In the high-load pivoting application test with 45MPa the wear was also the lowest by far. In practice, this means a substantial increase in service life and therefore less maintenance.
Load: 2 MPa
Speed: 0,3 m/s
Shaft: aluminium hc; Cf53; V2A; high-grade steel
Bearing materials: iglidur® G; iglidur® G1
After the wear test: only minor traces of wear are visible in the bearing.
After the wear test: The shaft only displays traces of solid lubricant transfer.
In rotating applications in the low-load range, iglidur® G1 displays considerably less wear on all tested shafts.
iglidur® G1 proves to be stronger, especially in the medium-high temperature range of 80°C to 120°C. As a result, iglidur® G1 allows a maximum surface pressure that is considerably higher than that allowed by iglidur® G.
The tests indicates considerably reduced levels of moisture absorption and saturation. Bearings made of iglidur® G1 change their shape much less due to swelling under water or in damp surroundings.
