What is the primary cause of false brinelling on a bearing?

The primary cause of false brinelling on a bearing is indeed vibration. False brinelling occurs when a bearing is subjected to vibrations while stationary. This can happen in situations where equipment is not in continuous operation, such as when a vehicle is idle or stored for a long period. The continuous motion in the presence of vibration leads to localized wear and indentation on the bearing surfaces, which resembles traditional brinelling caused by excessive loads.

Understanding this phenomenon is important because it highlights the need for proper handling and storing of equipment, especially large machinery or vehicles that may sit unused for extended periods. Recognizing that vibration alone can cause damage helps maintenance technicians take preventive measures, such as using stabilizing devices or ensuring proper support during storage.

While heat, radiation, and moisture can contribute to various forms of bearing wear or failure, they do not specifically lead to false brinelling. Instead, they are typically associated with other issues, such as overheating due to lubrication failure or corrosion from moisture exposure.
