NettetBearing failure modes . Much work has been done by the members of ISO Technical Committee TC4 to define the different failure modes and to classify them as shown here. This has resulted in ISO 15243, published in 2004. When looking at bearing failures, in total six main failure modes can be observed, which can be further classified into a NettetThe failure can result from improper transport, handling, mounting or maintenance or from faulty manufacture of the bearing or its adjacent parts. In some instances, failure is due to a design compromise made in the interests of economy or from unforeseen operating and environmental conditions.
