What does the +1.0mm sizing mean for this bearing set?

The +1.0mm sizing indicates that these bearings are designed to fit crankshaft journals that have been machined down by 1.0 millimeter. This is a common practice during engine rebuilding to correct wear or damage on the crankshaft.

What is the material of these bearings and why is it important?

These bearings are made from a bi-metal aluminum composite. This material is lead-free and considered environmentally safe, and it's particularly well-suited for medium-load engine applications.

Are these bearings suitable for high-performance or heavy-duty engines?

The manufacturer specifies that this bearing set is ideal for medium-load engines. For high-performance or very heavy-duty applications, it's always best to consult with a specialist to ensure the correct bearing material and load capacity are chosen.
