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

The '+0.75mm' indicates that these main bearings are 0.75mm larger in diameter than the standard size. This is typically used when the engine's crankshaft journals have been machined down (ground undersize) during a rebuild to clean up wear or damage.

What type of engine load are these bearings best suited for?

These bearings are specifically noted as being ideal for medium-load engines. This means they are well-suited for typical daily driving conditions and moderate performance use, balancing durability with material properties.

Are these bearings environmentally safe?

Yes, these bearings utilize a lead-free composite material, which is noted as being environmentally safe. This is a key feature of their construction.
