Crankshaft Bearing Material

The engine crankshaft bearings have layered structure. The bearings are crafted from robust materials such as alloyed aluminum or tri-metal composites, providing durability and resistance to wear.

The tri-metal bearings include 3 main layers (not include the flash layer and a steel back). It comprises,

1, Flash Layer: It’s the topmost layer, 1 micron thick, composed of tin and lead, and is used to protect the bearing from corrosion and dust when not in use. This layer flashes during bearing operation.
2, Overlay Layer: The second layer is made of metal tin-antimony copper, which is the main component of this type of bearing. Its thickness is 20 microns.
3, Interlay: The third layer is used as an anti-corrosion layer for the cover layer. Its thickness is 5 microns.
4, Lining Layer: The lining layer between the interplay and the steel back is 1mm thick and composed of lead and bronze.
