Q

Reciprocating air compressor bearing failure may result from __________.

🔍 Key Concepts

• bearing loads and alignment in reciprocating air compressors • effect of drive belt tension on shaft and bearing side loads • role of lubrication quality (sump oil contamination) in bearing life

💭 Think About

• For each option, ask yourself: would this condition increase stress or reduce lubrication on the bearings? If yes, could that reasonably lead to premature bearing failure? • Think about how misalignment between moving parts affects rolling or plain bearings in any rotating machinery, not just compressors. • Consider what happens to bearings when belts are much tighter than specified, and when dirty or contaminated oil circulates through them.

✅ Before You Answer

• For each of A, B, and C, decide individually if it could be a realistic cause of bearing failure in real machinery practice. • Verify whether side loading from belts can overload bearings even if everything else is in good condition. • Verify whether poor lubrication or contaminated oil is a well-known cause of bearing damage in rotating equipment.
