iglidur® J2 | Environmentally friendly, versatile and cost-effective
iglidur® J2 has good universal media resistance, comparable to that of iglidur® J and similar materials. The mechanical specifications in sporadically moved applications are better although, in comparison, clear compromises have to be made with regard to friction and wear. Like all iglidur® materials, iglidur® J2 is PFOA (perfluorooctanoic acid) free.

When to use it? When low moisture absorption and good chemical resistance is required for primarily static load When a cost-effective bearing is required for use in a wet environment with low PV values When there is basic lubrication of the bearing

When not to use it? When a highly wear-resistant bearing is required for continuous dry operation iglidur® J3, sleeve bearing, mm When low moisture absorption and media resistance play a minor role iglidur® M250, sleeve bearing, mm When resistance to high temperatures and chemicals is required iglidur® X, sleeve bearing, mm

Tolerances and measurement system
The installation dimensions and tolerances of iglidur® plain bearings are a function of the material and wall thicknesses. 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 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 in the correctly toleranced housing. The press-fit excess dimension can be up to 2% of the inner diameter. This ensures the secure press-fitting of the bearing. Axial or radial movement in the housing are prevented this way.
