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

This means the bearings are slightly thicker than standard by 1.0mm. They are used when the crankshaft journals have been machined down (ground undersize) during an engine rebuild to ensure proper oil clearance and a snug fit.

What is the construction of these main bearings?

These bearings feature a bimetal construction, which uses an aluminum alloy base. This design offers good load-carrying capacity and wear resistance, making them suitable for engine rebuilding.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings to rebuild the bottom end of the specified Volvo engines.
