What is the main purpose of main bearings?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the forces generated during combustion and power transfer.

What does 'Standard Size' mean for these bearings?

Standard size means these bearings are meant to be installed on a crankshaft that has not been machined or ground undersize. If your crankshaft has been reconditioned to a specific undersize (like -010 or -020), you would need a correspondingly sized bearing set.

Are these bearings suitable for high-performance or racing engines?

These bearings are described as ideal for low to medium-load engines. For high-performance or racing applications that experience extreme loads and higher RPMs, you might consider a different bearing material or series from King Engine Bearings.
