The crankshaft is exposed to high frictional forces when the engine is running. In order to sustain these forces for a long period of time, the crankshaft is mounted on specially-designed bearings, which with the help of a thin oil layer gives it the ability to rotate in its mounting places almost freely.
Of course, the bearings are made out of a more softer metal that the crankshaft’s journals so they will wear out at some point and they have to be replaced.
The easiest way to check their wear is to take out the whole crankshaft and measure them with a micrometer. You then check your measurements with the ones in the vehicle’s reparation manual and replace them according to their wear. Check the video bellow for more info.
