Introduction to Crankshaft Bearings

Crankshaft bearings, also commonly referred to as "main bearings" or "big end bearings", are the core sliding bearing components that directly support the crankshaft's main journals in an engine.
 
Basic Structure
 
Consists of two thin, semi-circular metal shells that combine to form a complete ring.
The back of the bearing is a steel substrate, while the inner surface is coated with a layer of anti-friction alloy, such as Babbitt, copper-lead alloy, or aluminum-based alloy.
This soft alloy layer not only reduces friction but also traps tiny contaminants in the lubricating oil, protecting the crankshaft from direct damage during temporary lubrication failure.
