Question

Bearings maintain very close tolerances and are likely to be damaged by an foreign abrasive material entering the lubrication line.

(a) True

(b) False

This question was addressed to me in homework.

My question is from Classification of Lubricating System in portion Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(a) True

Bearings maintain very close tolerances and are highly sensitive to damage from foreign abrasive materials entering the lubrication line. Contaminants in the oil can cause wear, reduce the efficiency of lubrication, and ultimately damage the bearings, leading to engine failure. This is why filtration of the lubricating oil is crucial in preventing such damage.
