The main bearing supports the crankshaft, reducing friction and ensuring smooth rotation under extreme loads. Regular maintenance includes monitoring oil pressure, checking for abnormal noises, and timely oil changes to prevent wear. Inspect bearings during major overhauls to avoid catastrophic engine failure and ensure optimal performance.
