What can excessive load in bearings lead to?

Excessive load in bearings can lead to increased wear and potential failure due to the stresses imposed on the bearing surfaces. When bearings are subjected to loads beyond their rated capacity, the material can experience fatigue, leading to surface degradation, overheating, and eventual failure. This happens because the excessive load causes higher friction and heat generation, which accelerates wear. The bearing surfaces may also become deformed under such loads, resulting in an increase in tolerances and possible misalignment. Over time, this can significantly decrease the lifespan of the bearings and potentially lead to catastrophic failure, affecting the machinery in which they are used.

Understanding the importance of load ratings and adhering to them can prevent these issues, ensuring that machinery operates reliably and efficiently.
