Table 01: Material data
When plain bearings need to be electrically conductive, especially in applications that should keep out static, iglidur® F is the right choice. Moreover, the iglidur® F plain bearings are extremely pressure-resistant. At room temperature, they could be statically loaded up to 105MPa.
Mechanical specification
The maximum recommended surface pressure represents a mechanical material parameter. The compressive strength of iglidur® F plain bearings decreases with increasing temperatures. diagram 02 illustrates this correlation. At the long-term permissible application temperature of +140 °C, the permissible surface pressure is still 50 MPa.
diagram. 03 shows the elastic deformation of iglidur® F under radial load. Under the maximum recommended surface pressure of 105 MPa, the deformation is less than 3.0 %.Plastic deformation can be ignored up to this pressure load. However, it also depends on the duration of the load.
Friction and wear
The coefficients of friction in dry operation are not as favourable with iglidur® F bearings as with various other iglidur® materials. However, iglidur®® bearings can be lubricated without hesitation, and in comparison with lubricated iglidur®® bearings, iglidur®® F bearings achieve excellent results.

Shaft materials
Diagrams 06 and 07 show an extension of the results of tests with different shaft materials carried out with plain bearings made from iglidur® F. In the lowest load range, the hard-chrome plated shaft proves to be the most favourable mating partner for rotating applications with iglidur® F plain bearings.
