What is a common sign of bearing failure?

A common sign of bearing failure is the presence of unusual noise and excessive vibration. When bearings begin to fail, they often do so due to wear and tear, contamination, or misalignment. These issues can create irregular motion or friction, resulting in sounds such as grinding, knocking, or whining. Excessive vibration is another indicator, as it typically arises when the load on the bearing is unevenly distributed, or when there are loose components or damaged surfaces within the bearing assembly.

Monitoring these signs is crucial because they can lead to more severe damage if not addressed promptly. Detecting unusual noise and excessive vibration early on can help in taking corrective action, thereby preventing unexpected downtime and further damage to the machinery.
