Any internal combustion engine contains dozens of fast-spinning parts, and its lubrication system is designed to eliminate or minimize metal-to-metal contact between them. But still, friction remains one of the main enemies of the motor, as direct contact between metal components does occur anyway. Taking the brunt of such contact, engine bearings belong to those ingenious solutions allowing the motor to successfully operate for hundreds of thousands of miles instead of just hundreds or even less. Most bearings used in the engine are of a sliding type. In fact, any of them can be compared to a metal shim, but this shim features a special configuration and consists of several materials, which helps to maintain or even improve lubrication quality.
These materials are carefully selected according to the expected loads and engine lifespan. Most production cars come from the factory equipped with bimetal bearings having two layers, a steel back and relatively softer overlay. As for high-performance and racing machines, it's often sensible to install the bearings having a trimetal construction, which includes steel back, copper-lead intermediate material, and third layer depending on a planned application. Such bearings are not as hard and durable as bimetal ones, but that's the point – they allow the crankshaft and other parts to survive under extreme loads appearing at high RPM or during hard acceleration.
Holes and grooves in engine bearings are made for the most efficient lubrication, but it's recommended to properly select bearing clearances and oil viscosity. Less viscous motor oils can be better for power or fuel economy, but they require tighter clearances. The modern industry constantly offers more refined and efficient oils meant to diminish abrasion, as well as new racing bearings.
