What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining proper oil clearance, which is critical for reducing friction and wear.

What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are manufactured to the original equipment manufacturer's (OEM) specifications for the crankshaft journal diameter and the main bore diameter.

What is the XP series designation?

The XP series indicates a specific construction from King Engine Bearings, featuring a specialized overlay material. This overlay is designed for enhanced durability and wear resistance, helping to protect the bearing surfaces under demanding conditions.
