iglide® A290 polymer flange bearing, metric

iglide® A290 | Robust, with high abrasion resistance
 

• Complies with the requirements of the BfR (German Federal Institute for Risk Assessment)
• For direct contact with food
• Good abrasion resistance
• If low noise level is required
• Dry-running and maintenance-free
• Standard range from stock

iglide® A290 bearings are an advanced development for the use in food industry. Compared to the bearings made from iglide® A200, the tribological properties are significantly improved.

When to use it? Suitable for contact with food For low speeds If low noise level is required Physiologically safe Very good mechanical properties

When not to use? When the material’s FDA compliance is necessary When the highest wear resistance is required When temperatures are continuously higher than +284 °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.
