Which issue can arise from insufficient lubrication in bearings?

Insufficient lubrication in bearings can lead to overheating, wear, and eventual failure of the bearing. Lubrication is essential for reducing friction between the moving parts within the bearing. When there is not enough lubricant, the metal surfaces can come into direct contact with each other, increasing friction and heat generation. This excessive heat can cause the lubricant to break down or evaporate further, leading to inadequate lubrication and creating a cycle of increased wear and tear.

As the bearing continues to operate under these poor conditions, it may suffer from increased wear of the rolling surfaces, leading to pitting and surface damage. Over time, this deterioration can compromise the structural integrity of the bearing, resulting in failure and potentially causing damage to other components of the machinery. Therefore, ensuring proper lubrication is critical for maintaining the function and longevity of bearings within any mechanical system.
