Tolerances and measuring system
The installation dimensions and tolerances of the iglidur® plain bearings depend on the material and wall thickness. 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.
Testing methods

Assembly
iglidur® plain bearings are press-fit bearings. The inner diameter is only adjusted to the appropriate tolerance after pressing into the housing. 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 reliably avoided.
