What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a precise oil film between the crankshaft journals and the bearing surface, allowing the crankshaft to rotate smoothly with minimal friction and wear.

What does 'main bearing set' mean?

A main bearing set includes all the individual main bearings needed to replace the ones supporting the crankshaft in your engine. This ensures you have the correct parts for a complete replacement.

Are these bearings undersized or oversized?

This is a standard size main bearing set (MS109P10). If your crankshaft has been machined undersize due to wear or damage, you would need a different bearing set with an appropriate undersize.
