What does '+0.50 Oversize' mean for these bearings?

This means the bearings are 0.50mm larger in diameter than standard size. This is typically used when the crankshaft journals have been machined down to remove wear or damage during an engine rebuild.

What is the main purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a precise oil clearance that allows the crankshaft to spin smoothly while maintaining proper lubrication and support.

Are these bearings sold individually or as a set?

This is a set of main bearings, meaning it includes all the necessary bearings to replace the main bearings for your engine's crankshaft.
