iglidur® Q290 | for moderate to high loads, especially on soft shafts
iglidur® Q290 shows outstanding service life in robust swivel applications, as they are frequently found in some agricultural machinery, especially on "soft" shafts (e.g. galvanised). The wear on the shafts is minimal.

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.
