iglidur® A290, sleeve bearing, mm

iglidur® A290 | Robust, with high abrasion resistance
 

• Abrasion-resistant
• If low noise level is required
• Lubrication- and maintenance-free
• Standard range from stock

iglidur® A290 plain bearings were developed for good resistance to wear and quiet operation. Compared to bearings made from iglidur® A200, the tribological and mechanical properties have been significantly improved.

Tolerances and measuring system
The installation height and tolerances of iglidur® plain bearings are dependent on 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 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 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 is also prevented this way.
