For each material, the moisture absorption and the thermal expansion are decisive factors. Plain bearings with low moisture absorption can be installed with a smaller bearing clearance. The rule for wall thickness: the thicker the wall of the bearings, the larger the clearances must be. <a href="/l/plain-bearing/wiki/tolerances">Testing methods</a> Assembly iglidur® plain bearings are press-fit bearings. The inner diameter is only adjusted to the appropriate tolerance after pressing into the housing hole. The press-fit excess dimension can be up to 2% of the inner diameter. This ensures the secure press-fitting of the bearings. Axial or radial movements in the housing are thus reliably avoided. <a href="/l/plain-bearing/wiki/tolerances">iglidur® - assembling, gluing, machining</a> &nbsp;
