What does the 0.75 undersize mean for my engine rebuild?

The 0.75 undersize indicates that these bearings are designed for a crankshaft that has been machined down by 0.00075 inches. This is a common practice during engine rebuilds to achieve precise oil clearance when the original crankshaft journals have wear or have been re-ground.

Are these bearings sold individually or as a set?

This is a set of four connecting rod bearings, which is the standard quantity needed for a four-cylinder engine like the BMW B48A20B.

What is the typical application for these bearings?

These bearings are commonly used during engine rebuilds or performance builds where the connecting rod journals on the crankshaft have been machined to a specific undersize to ensure proper oil clearance and bearing performance.
