What can result from insufficient lubrication in bearings?

Insufficient lubrication in bearings primarily leads to higher friction and increases the risk of potential failure. Lubrication plays a crucial role in minimizing contact between the moving parts of a bearing, reducing wear, and ensuring that heat is dissipated effectively. Without adequate lubrication, metal-to-metal contact can occur, which generates significant friction. This not only leads to rapid degradation of the bearing surfaces but can also result in overheating, which can cause the bearing to seize or fail completely.

Proper lubrication not only reduces friction but also helps in protecting against contaminants and provides a film that prevents corrosion. Thus, the consequences of insufficient lubrication manifest through increased wear, heat generation, and ultimately a higher likelihood of failure, which can compromise the entire machinery's operation.
