How can the Brinelling of a bearing be identified?

Brinelling of a bearing can be identified primarily by the presence of indentations pressed into the bearing race. This phenomenon occurs when the bearing is subjected to excessive static or dynamic loads, leading to permanent deformation of the race surface. The resulting indentations can typically be observed visually on the inner or outer race, which helps differentiate Brinelling from other potential issues.

For instance, while color discoloration may indicate overheating or the presence of contaminants, it is not a definitive sign of Brinelling. Excessive noise production can result from various bearing failures, including improper lubrication or misalignment, but it does not specifically indicate Brinelling. Similarly, overheating during operation could be caused by several factors, and while it might coincide with Brinelling if the failure leads to friction and heat generation, it is not a direct identification method. The distinct indentations created on the races are the primary clear indicator of Brinelling, making this observation crucial for maintenance and diagnostic procedures in machinery involving bearings.
