What is a common failure mode of bearings in mechanical systems?

Wear due to inadequate lubrication or contamination is a common failure mode of bearings in mechanical systems. Bearings rely on a thin film of lubricant to operate effectively, reducing friction and preventing metal-to-metal contact. Insufficient lubrication can lead to increased friction and heat, accelerating wear and damaging the bearing surfaces. Additionally, contamination from particles or debris can compromise the lubricant's effectiveness, resulting in abrasive wear and further degradation of the bearing material.

This phenomenon is particularly critical as it can lead to catastrophic failure of mechanical systems if not addressed. Regular maintenance, proper lubrication practices, and using clean environments are essential to prolonging the life of bearings and ensuring reliable operation in machinery.

The other options represent potential issues but are less universally applicable as primary failure modes in bearings compared to wear due to lack of lubrication and contamination. Overheating due to excessive load may occur but is not as common as lubrication-related wear. Corrosion and excessive noise may indicate problems, but they typically arise as secondary effects of initial wear and degradation.
