What does the '+0.75mm' size mean for these bearings?

The '+0.75mm' designation means these bearings are designed for use when the crankshaft journals have been machined down by 0.75mm. This is a common practice during engine rebuilding to ensure proper oil clearance with worn or reconditioned crankshafts.

What is a bimetal bearing?

A bimetal bearing, like this one with an aluminum base, is constructed from multiple layers of material. This design allows for a combination of strength, wear resistance, and conformability to the crankshaft, which is essential for effective lubrication and reduced friction in an engine.

Are these bearings sold individually or as a set?

This product is sold as a main bearing set. A set typically includes all the main bearings needed for a complete engine installation.
