iglidur® X - Material data

Mechanical specifications

The compressive strength of iglidur X plain bearings decreases with increasing temperatures. Diagram 02 illustrates this relationship. At the long-term permissible application temperature of +250°C, the permissible surface pressure is approximately 30MPa. The maximum recommended surface pressure represents a mechanical material parameter. No conclusions can be drawn about the tribology. With a maximum recommended surface pressure of 35MPa, iglidur X plain bearings are not suitable for extreme loads. Diagram 03 shows the elastic deformation of iglidur X under radial loads.

Shaft materials

Friction and wear are also highly dependent on the mating partner. Shafts that are too smooth increase the coefficient of friction of the bearing. Smoothed surfaces with an average surface finish Ra of 0.6 to 0.8μm are ideal.

Diagrams 06 and 07 show an extension of the results of tests with different shaft materials that were carried out with iglidur® X plain bearings. If the shaft material you intend to use is not included in the test results presented here, please contact us.
