iglidur® H4 | The automotive standard for temperatures up to +200°C
iglidur® H4 bearings stand for high load carrying capacity, good abrasion and temperature resistance, as well as the obvious economic factors. Temperatures up to +200° C, permitted surface pressure up to 65 MPa, and excellent chemical resistance are only some of the ket features. Solid lubricants lower the coefficient of friction and support the wear resistance, which was essentially improved compared to the similar cost-effective iglidur® H2 bearings.

Tolerances and measurement system
The installation dimensions and tolerances of iglidur® plain bearings are a function of the material and wall thicknesses. For each material, the moisture absorption and the thermal expansion are decisive factors. Plain bearings with low moisture absorption can be designed with a minimal bearing clearance. The rule for wall thickness: the thicker the wall of the bearings, the larger the clearances must be.
Testing methods
 
Assembly
iglidur® plain bearings are press-fit bearings. The inner diameter adjusts only after press-fitting in the correctly toleranced housing. The press-fit excess dimension can be up to 2% of the inner diameter. This ensures the secure press-fitting of the bearing. Axial or radial movement in the housing are prevented this way.
