How much does moisture affect the life of bearing accessories?

The smooth operation of bearings relies on proper lubrication, yet the potential damage that moisture can cause to bearings often goes unnoticed. In fact, moisture has a significant impact on the service life of bearings, and even trace amounts can lead to a substantial reduction in the lifespan of rolling bearings. On the one hand, water directly corrodes metal surfaces, and on the other hand, it can damage lubricating oil or grease, leading to bearing damage.

Moisture can cause rust on the surface of the metal, and for lubricants such as oil, moisture can cause the oil to oxidize and deteriorate, eventually generating corrosive acids that damage the metal. Furthermore, water can also cause oil to oxidize and deteriorate, then affect the viscosity and fluidity of the oil, and finally, the continuous accumulation of moisture can lead to a chain of problems, resulting in a greater harm issue.
