Grease lubrication of bearings in humid environments

Core Tip: In a humid environment, condensate can form in the rolling bearing and cause corrosion, resulting in shortened bearing life. By carefully selecting the grease to lubricate, the effect of condensation moisture can be reduced.

In a humid environment, condensate forms in the rolling bearing and causes corrosion, resulting in a shortened bearing life. By carefully selecting the grease to lubricate, the effect of condensation moisture can be reduced. The fat thickened with sodium soap has a strong ability to absorb water vapor, but softens due to too much moisture absorption, and flows out of the bearing; although lithium soap does not absorb moisture, it is added by appropriate additives. Provides good corrosion protection, and some greases containing synthetic thickeners also provide excellent corrosion resistance and extend bearing life.
