1. Surface cleaning: Cleaning must combine the nature of the surface of the high temperature bearing with the conditions at that time. The commonly used methods are solvent cleaning, mechanical cleaning and chemical treatment cleaning.
2. After the surface is dry and clean, it can be dried by filtering dry compressed air. Or use a drier to dry at a temperature of 120 ~ 170 ℃, and finally wipe it with a clean gauze.
Doing the inspection and maintenance of the bearing normally will avoid many problems and prolong the service life of the bearing. Bearing corrosion is very common and it reduces bearing life. So everyone must pay attention to this problem in daily work.
