What does the +0.50mm sizing mean for these main bearings?

The +0.50mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.50mm. This is a common practice during engine rebuilding to correct wear or out-of-round conditions on the crankshaft.

What is the construction of these King Engine Bearings?

These bearings feature a bimetal construction with an aluminum base. This design is chosen for its good oil retention properties and wear resistance, which are crucial for the longevity of main bearings.

Are these bearings suitable for a standard M10 engine rebuild?

Yes, these bearings are designed for BMW M10B15, M10B18, and M10B20 engines. They are a popular choice for engine rebuilds, especially when the crankshaft has been machined to a 0.50mm undersize.
