With proper lubrication and alignment, main bearings typically last 20,000-50,000 operating hours. Lifespan depends on load conditions, speed, and environmental factors.
Common signs include increased vibration, abnormal noise (grinding or humming), temperature rise above 70°C, and visible pitting or discoloration on bearing surfaces.
