What does the +0.75mm sizing mean for these main bearings?

The +0.75mm sizing indicates that these bearings are intended for use when the engine's crankshaft main journals have been machined down by 0.75mm. This is typically done during an engine rebuild to clean up wear or minor damage on the journals.

What are these bearings made of?

These main bearings are made from a bimetal material with an aluminum silicon base. This construction is chosen for its ability to handle the loads and temperatures within the engine's crankcase.

Are these bearings suitable for a stock engine rebuild?
