False Brinelling

Glossary Term

Definition and Purpose

False Brinelling is a specific type of fretting wear that occurs in rolling element bearings when they are subjected to vibrations of small amplitude while under load. This phenomenon leads to the formation of depressions on the bearing raceways that resemble the marks left by Brinell hardness testing, despite being caused by a different mechanism. The process involves the welding and separation of microscopic surface asperities, followed by the generation and oxidation of wear particles, which then contribute to abrasive wear.
