What does the 0.25mm undersize mean for these bearings?

An undersize bearing is used when the crankshaft journals have been machined down to correct for wear or damage. The 0.25mm indicates how much smaller the bearing is compared to a standard size, matching the amount the crankshaft journals have been turned down.

What material are these bearings made from?

These bearings are made from King's SV material, which is a multi-layer design intended for durability and consistent performance under engine load.

Are these bearings sold individually or as a set?

This is a set of four connecting rod bearings, suitable for a four-cylinder engine like the BMW B48A20B.
