What is False Brinelling in the context of bearings?

False Brinelling is a specific type of wear that occurs in rolling element bearings when they are subjected to vibration while stationary. This phenomenon is typically observed when the machine is not in operation for prolonged periods, but external vibrations (such as from nearby equipment or transportation) cause rhythmic oscillations in the bearing elements. As a result, small indentations or wear patterns form on the raceways and rolling elements, resembling the damage seen in true Brinelling, which is typically associated with excessive load or shock loading.

Understanding this concept is important because it highlights the need for proper maintenance and operational practices to minimize vibration exposure to stationary equipment. This knowledge can guide engineers in implementing effective strategies to mitigate such wear, such as using isolation techniques to reduce vibration or instituting rotation schedules for idle machinery.
