What does '1.0mm oversize' mean for these bearings?

This means the bearings are manufactured to be 1.0mm larger in diameter than standard. They are intended for use when the crankshaft's main journals have been machined down by 1.0mm to correct wear or damage.

What are these bearings made of?

These bearings feature a bimetal construction, utilizing an aluminum silicon base. This material is chosen for its ability to handle engine loads and temperatures.

Do I need to buy anything else with these bearings?

When replacing main bearings, it's highly recommended to also replace the engine oil and oil filter. You may also need assembly lube to properly coat the bearings before installation.
