What is the main function of crankshaft main bearings?

Crankshaft main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining proper oil clearance for lubrication.

What does 'main bearing set' mean?

A main bearing set includes all the individual bearings needed to support the crankshaft's main journals. This ensures consistent support and lubrication across the entire rotating assembly.

Are these bearings undersized or oversized?

This ACL 4M2021P-20 main bearing set is a standard size. It is designed to be used with a crankshaft that is within factory specifications. Always check your crankshaft journals for wear or damage before installation.
