Burn fault and solution of bearing

Burn fault and solution of bearing
The so-called burn damage state of  bearings refers to the rapid heating of the raceway wheel, rolling element, and retainer of  bearings during rotation until discoloration, softening, deposition, and damage occur.The main reason for bearing burns is due to poor lubrication of  bearings, which may have used non-standard lubricants or excessive or insufficient lubricants, both of which are incorrect. Secondly, it may be due to excessive load (excessive preloading). The rotational speed is too high. The clearance is too small. There is water or other foreign objects invading.
What material is bearing steel？

What material is bearing steel？
What material is bearing steelBearing steel is a steel used to manufacture balls, rollers, and bearing rings. Bearing steel has high and uniform hardness, wear resistance, and high elastic limit. Strict requirements are placed on the uniformity of chemical composition, content and distribution of non-metallic inclusions, and distribution of carbides in bearing steel, making it one of the most stringent steel grades in all steel production.
