iglide® RW370 polymer flange bearing, metric

iglidur® RW370 | Wear-resistant for rail technology
 
The first iglidur® material that fulfils the European fire safety standard for rail vehicles is suitable for many wear-stressed applications in railway technology due to its very complete property profile.
 
Typical application areas
Furniture/Industrial design
Public transport engineering
 

When to use it? For applications in rail technology where suitability according to DIN EN 45545 is required For highest wear resistance at low to medium pressure loads When low coefficient of friction in dry operation is required Low moisture absorption

When not to use it? When high pressure loads occur and suitability according to DIN EN 45545 is not needed When short-term temperatures higher than +190°C occur When a cost-effective bearing for occasional movements is necessary

 
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 bearing clearance. The rule for wall thickness: the thicker the wall of the bearings, the larger the clearances must be.
 
Assembly
iglidur® bearings are press-fit bearings. The inner diameter adjusts only after press-fit 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.
