Which effect on lubrication performance develops when a journal bearing excessively heats?

💡 Explanation

Decreasing temperature drops viscosity, thinning the lubrication film and increasing flow because of increased hydrodynamic resistance. This reduces the load-carrying capacity creating leakage; therefore, the bearing fails rather than oxidizing or solidifying which require different chemical regimes.
