Science

Which risk increases upon molecular contamination within bearings?

A)Rolling contact fatigue accelerates
B)Increased lubricant thermal runaway
C)Decreased rotor critical speed
D)Accelerated vibrational frequency response

💡 Explanation

Rolling contact fatigue accelerates because the Rebinder effect (adsorption-induced reduction in material strength) weakens bonds. Therefore, the fatigue accelerates, rather than thermal runaway, because intermolecular forces are affected, not lubricant viscosity mechanics.
