iglidur® M250 | The robust all-rounder with excellent vibration dampening
The self-lubricating plain bearings made of iglidur® M250 are characterised by impact strength, vibration dampening and wear resistance. They prove themselves particularly well under stresses in which the vibration dampening of the bearings is required, e. g. in sports equipment and packaging machines. Since they are also capable of embedding dirt, they are also well suited in agricultural machinery and gardening equipment.

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 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.
