What is the purpose of crankshaft main bearings?

Crankshaft main bearings are crucial for engine longevity. They support the crankshaft within the engine block, allowing it to rotate smoothly while handling significant loads and reducing friction.

What does the 'full groove' design mean for these bearings?

A full groove design helps to distribute lubricating oil more evenly around the entire circumference of the bearing. This ensures consistent oil film thickness, which is vital for reducing wear and heat.

Are these bearings a standard size or undersize?

This bearing set is a standard size. If your crankshaft has been machined undersize due to wear or damage, you would need a different bearing set with a corresponding undersize measurement.
