Maximum recommended surface pressure represents a mechanical material parameter. Tribological conclusions cannot be drawn from it. With increasing temperatures, the compressive strength of iglidur® A500 bearings decreases. Fig. 02 clarifies this connection. With the long-term permitted application temperature of +250℃, the permitted surface pressure is less than 11 MPa.
Plain bearings made of iglidur® A500 can be used at very high temperatures and are permitted for use in direct contact with foodstuffs (FDA compliant). They exhibit an exceptionally good chemical resistance and are suitable for heavy-duty use in machinery for the food industry. Though iglidur® A500 is an extremely tough material, it simultaneously possesses excellent compressive strength even at high temperatures. Figure 02 shows the maximum recommended surface pressure of the bearing dependent on the temperature. This combination of high stability and high flexibility acts very positively during vibrations and edge loads. As the wear of the bearing rapidly escalates from pressures of 10 to 20 MPa, we recommend a particularly accurate testing of the application above these limits.
