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

The +0.50mm designation indicates that these bearings are designed for use when the crankshaft journals have been machined down by 0.50mm. This is a common practice during engine rebuilds to true up worn or damaged crankshaft surfaces.

What is the bimetal construction with an aluminum base?

Bimetal bearings typically consist of a steel backing for strength and a bearing material layer on top. In this case, the bearing material is an aluminum-based alloy, chosen for its good load-carrying capacity and compatibility with crankshaft surfaces.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes all the necessary bearings for the connecting rods on your engine.

About this part

Product Details

These connecting rod bearings are built with a bimetal construction, featuring an aluminum base. This design is specifically for the Ford Fiesta 1.25I with the ZETec engine, and this set is machined to a +0.50mm size, meaning they are intended for use when the crankshaft journals have been ground down by 0.50mm during an engine rebuild.

King Engine Bearings uses this bimetal approach to offer a solid balance of strength and performance for engine internals. When you're rebuilding the bottom end of your ZETec engine, properly sized and well-built bearings are crucial for ensuring smooth operation and longevity. These bearings are designed to handle the loads and temperatures within the engine, helping to maintain proper oil clearance between the connecting rod and the crankshaft.
