What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are intended for use when the main journals on your engine's crankshaft have been machined to be 0.50mm larger than their original size. This is a common practice during engine rebuilds to restore proper clearances.

What is the primary function of main bearings?

Main bearings support the crankshaft within the engine block. They create the necessary oil clearance between the crankshaft journals and the block, allowing the crankshaft to rotate smoothly while maintaining proper lubrication.

Are these bearings suitable for a stock engine rebuild?

These bearings are specifically sized at +0.50mm, meaning they are for engines where the crankshaft has already been machined to this oversize. If your crankshaft is still at standard size, you would need a standard-sized bearing set.
