What does the +0.75mm sizing mean for these bearings?

The +0.75mm designation indicates that these main bearings are 0.75mm undersize compared to standard bearings. This sizing is used when the crankshaft journals have been machined undersize to correct wear or damage.

What is a bimetal bearing construction?

Bimetal bearings, like these from King Engine Bearings, use a layered construction with an aluminum base. This design offers good performance characteristics, including wear resistance and the ability to conform to the crankshaft, which is important for proper oil film formation.

Are these bearings suitable for a performance rebuild?

These bearings are a well-built option for engine rebuilding. The bimetal construction is a common choice for many applications, offering a balance of durability and performance for the Ka-24E engine.
