What is the function of crankshaft bearings?

[OCharles]

The function of crankshaft bearings is to support and fix the crankshaft. Crankshaft bearings ensure long-term operation of the crankshaft: Because there is a very small gap between them and the crankshaft, when the engine crankshaft rotates at high speed, a layer of oil film in the gap separates the crankshaft from the bearings, ensuring long-term operation of the crankshaft without damage. Effects of crankshaft bearing wear: Abnormal oil pressure, most components inside the engine use pressure lubrication. In addition to the oil pump delivering oil, many components are designed with oil passages that rely on changes in the relative positions of the components to create a vacuum and guide the flow of oil. For example, the crankshaft and connecting rods are designed with internal oil passages, and these components need to maintain correct clearances to ensure proper lubrication.
