Tolerances and measuring system
The installation height and tolerances of iglidur® plain bearings are dependent 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 designed with a minimal bearing clearance. The rule of thumb 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 into the correctly toleranced housing hole. The press-fit interference can be up to 2% of the inner diameter. This ensures that the bearing is securely press-fitted. Axial or radial movements in the housing are also prevented in this way.
