iglide® A181 polymer flange bearing, metric

iglide® A181 | The universal bearing for contact with food

PFAS-tested: All iglide materials labeled as "PFAS-tested" were tested for 96 PFAS substances considered critical for the environment and health. This category excludes substances from the group of fluoropolymers.

• Compliant with EC directive 10/2011 EC
• FDA-compliant
• Universal use
• Good liquid media resistance
• Wear resistant
• Dry-running and maintenance-free
• Standard range from stock

The iglide® A181 material is food compliant with directive 10/2011 EC and also to FDA specifications. The blue color also facilitates the often required "optical detectability" in the food industry. Compared to iglide® A180 with regard to the mechanical properties, temperature and media resistance, iglide® A181 is more suitable with respect to the wear resistance in most cases.
  

When to use it? When FDA compliance is required When a material compliant with the 10/2011 EC is required When an universal material suitable for direct contact with food is required

When not to use? When FDA and 10/2011 EC Directive compliance are not required When temperatures are continuously higher than +194 °F When a cost-effective universal bearing is required

Tolerances and measurement system
The installation dimensions and tolerances of the iglide® 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.
 
Assembly
iglide® 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.
