Briefly explain what material the engine crankshaft bearing is made of.

Generally, they are all kinds of alloys, and different products use different alloys, such as Moguyi, and some have steel back alloy surfaces. What are the specific alloy surfaces? What are the specific proportions of metals and alloys? Only the manufacturer knows.

Anyway, where? Housing) is the contact part between the sliding bearing and the journal. It is a tile-shaped semi-cylindrical surface, which is very smooth. Generally made of wear-resistant materials such as bronze and antifriction alloy. It can be made of wood, engineering plastics or rubber under special circumstances.

Anyway, no matter what material is used, it is for wear resistance, low friction coefficient and easy manufacture. , for all kinds of balance.
