What are common causes of bearing failure?

Inadequate lubrication is a common cause of bearing failure, primarily because lubrication serves critical functions in the operation of bearings. It reduces friction between moving parts, helps dissipate heat generated during operation, and protects against contamination. When lubrication is insufficient, bearings may experience increased wear and tear due to metal-to-metal contact, leading to premature failure. This condition can exacerbate other issues, such as overheating and structural integrity failures.

Over time, if bearings are not properly lubricated, they can develop surface imperfections, overheating problems, and ultimately fatigue, which can significantly shorten their lifespan. Adequate lubrication not only helps ensure smooth operation but also enhances the reliability and efficiency of machinery components. Therefore, the absence of proper lubrication can be a direct pathway to bearing failure and it's crucial for maintenance practices to incorporate sufficient lubrication protocols to prevent these issues.
