High loads and speeds can generate excessive heat, so consider reducing them if possible.

Improve cooling:

Consider using cooling systems such as fans, coolers, or air conditioning to reduce the ambient temperature around the bearing.

Contamination 

Dirt, debris, and other contaminants can damage bearings and reduce their lifespan. Bearings are designed to operate with a thin film of lubricant between the rolling elements and raceways. 

Any contaminants in this lubricant can cause abrasive wear, leading to premature failure. In addition, contaminants can also cause corrosion, pitting, and other damage to the bearing surfaces.

Contaminants can enter the bearing in a variety of ways, including through the seals, during installation or maintenance, or from the operating environment.

To prevent dirt, debris, and other contaminants from damaging bearings, We can follow below mentioned points
