WebThe definition of brinelling is the permanent indentation of a hard surface. Bearing brinelling occurs when the internal raceways of a bearing have been permanently damaged. The indentations can quickly lead to improper operation, like chattering or excess vibration, which in turn can accelerate other forms of wear. WebThe basic cause of false brinelling is that the design of the bearing does not have a method for redistribution of lubricant without large rotational movement of all bearing surfaces in the raceway. …. Without lubricant, wear is increased when the small oscillatory movements occur again.

WebEdward Jones Making Sense of Investing WebApr 15, 2024 · False brinelling is a type of fretting wear mechanism that causes damage to the raceways of rolling bearings exposed to environmental vibrations while the bearing is stationary. The vibrations induce small movements of the rolling elements, which squeeze lubricant out of the gap between the roller and the raceway allowing metal-to-metal …
