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

The +0.50mm sizing means these bearings are larger than standard size. They are designed to be used when the engine's crankshaft connecting rod journals have been machined down by 0.50mm, typically during an engine rebuild to restore proper oil clearance and performance.

What is the construction of these connecting rod bearings?

These bearings feature a bimetal construction with an aluminum silicon base. This type of material is well-suited for engine bearings, offering good wear resistance and thermal properties.

Are these bearings sold individually or as a set?

This product is sold as a set of connecting rod bearings. A set typically includes enough bearings to replace all connecting rod bearings for one engine.
