Which risk increases when lubricating oil viscosity declines in bearings?

💡 Explanation

Reduced oil viscosity lowers fluid's resistance to flow; therefore the hydrodynamic lubrication weakens; causing less pressure support to separate bearing surfaces because the effective load-bearing film reduces rather than a chemical change.
