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

This means the bearings are designed for a crankshaft that has been machined down by 1.0mm. This is typically done to correct for wear or damage on the original crankshaft journals. You must use these bearings only if your crankshaft has been professionally ground to this specific undersize.

What is the material of these main bearings?

These bearings are made with a bimetal construction that features an aluminum silicon base. This material is chosen for its good wear resistance and ability to handle engine operating temperatures.

Do these bearings come with new main bolts?

This listing is for the main bearing set only. It does not include new main cap bolts. It is recommended to consult your vehicle's service manual for specific installation procedures and any additional hardware that may be required.
