What does 'bearing seizure' mean?
1 Answers
Bearing seizure refers to the abnormal wear of engine bearings caused by insufficient lubrication. When bearing seizure occurs in an engine, noticeable scratches will appear on the bearings. During operation, an engine requires oil lubrication. Under normal working conditions, a layer of oil film forms on the surfaces of various components inside the engine to prevent direct contact between parts and reduce friction resistance. Bearing seizure is typically caused by excessive engine temperature or poor lubrication. Symptoms of bearing seizure include: 1. Severe lack of lubricating oil during engine operation; 2. Degraded engine oil that fails to provide proper lubrication; 3. Low or no oil pressure while the engine continues to run; 4. Presence of bearing alloy fragments in the engine's crankcase oil.
