iglidur® G1 wear test

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.

Up to 75% reduction in wear in pivoting applications on very different shafts

The wear comparison was carried out under the following test parameters:

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

Coefficient of wear in micrograms/cubic metre

Wear, pivoting: load 2 MPa, speed 0.01 m/s, y-axis: coefficient of wear [μm/km]

Coefficient of wear in micrograms/cubic metre

Wear, pivoting: load 45 MPa, speed 0.01 m/s, shaft material: Cf53, y-axis: coefficient of wear [μm/km]

Coefficients of friction of iglidur® G and iglidur® G1

Coefficient of friction, pivoting: load 2 MPa, speed 0.01 m/s y-axis; coefficient of friction [μ]


Test result

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.

Reduced wear in rotation tests as well

The wear comparison was carried out under the following test parameters:

Load: 2 MPa

Speed: 0,3 m/s

Temperature: 23°C

Shaft: aluminium hc; Cf53; V2A; high-grade steel

Bearing materials: iglidur® G; iglidur® G1

rotating wear - iglidur® G update

Wear, rotating: load 2 MPa, speed 0.3 m/s
y-axis: coefficient of wear [μm/km]

Test result

In rotating applications in the low-load range, iglidur® G1 displays considerably less wear on all tested shafts.

Results of the high-temperature surface pressure tests

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.

Surface pressure at high temperatures  

Results of the moisture absorption test

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.
