iglidur® J4 | Low-cost material
Tolerances and measurement system
The installation dimensions and tolerances of the iglidur® plain bearings are a function of the material and wall thicknesses. For each material, the moisture absorption and the thermal expansion are imperative. Plain bearings with low moisture absorption can be designed with a minimal amount of tolerance. For wall thickness, the rule is: The thicker the bearings are, the larger the tolerances must be.
Testing methods
Assembly
iglidur® bearings are press-fit bearings. The inner diameter adjusts only after press-fit in the proper housing bore with a recommended tolerance. The before press-fit oversized dimension can be up to 2% of the inner diameter. In this manner, the secure press-fitting of the bearing is achieved. Axial or radial shifts in the housing are also prevented.
