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

The +0.50mm designation indicates that these bearings are 0.50mm larger than standard size. This is typically used when the crankshaft journals have been machined down (ground) by 0.50mm during an engine rebuild to remove wear or damage.

What is the advantage of a bi-metal aluminum material?

Bi-metal construction typically involves a steel backing for strength and a bearing material layer, often aluminum-based, for good embeddability and compatibility with the crankshaft. This combination offers a good balance of durability and performance for many engine applications.

Are these bearings environmentally safe?

Yes, these bearings are made with a lead-free composite, which is considered environmentally safe. This is a notable feature, especially for builders looking to use materials that meet modern environmental standards.
