What is the general effect of increased load on a bearing?

Increased load on a bearing typically results in increased heat generation and wear. When a bearing operates under higher loads, the contact pressure between the rolling elements and the raceways increases, leading to greater friction. This added friction generates more heat, which can affect the lubricant’s effectiveness and potentially lead to overheating of the bearing.

As the temperature rises, the lubricant may degrade faster, and the bearing surfaces can suffer from accelerated wear due to the increased stress from the load. Over time, this can lead to reduced performance, premature failure, or the need for more frequent maintenance. Understanding this relationship is crucial for maintaining optimal bearing performance and ensuring machine longevity, as excessive heat and wear can significantly shorten the service life of the bearing.
