What does the +1.0mm sizing mean for this main bearing set?

The +1.0mm sizing indicates that these bearings are intended for use with a crankshaft that has been machined down by 1.0mm. This is a common practice during engine rebuilds to ensure a fresh, perfectly round surface for the bearings to operate on.

What is the construction of these main bearings?

These main bearings are constructed using a bimetal design. This means they have a strong aluminum base, which is a well-tested material for handling the significant loads and temperatures encountered in an engine's main bearing journals.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for a complete engine rebuild of the specified Opel engines.

Product Details

When you're rebuilding the bottom end of your engine, a solid set of main bearings is crucial. This set from King Engine Bearings is specifically made for Opel C20Xe, X18Xe, and X22Xe engines, and it's sized at +1.0mm, meaning it's designed to be used with a crankshaft that has been machined down by 1.0mm.

King Engine Bearings is a well-known name in the engine component world, and this set is built to handle the demands of engine operation. The +1.0mm sizing indicates these are intended for use after a crankshaft has been reground, a standard procedure when rebuilding an engine to ensure a fresh, perfectly round surface for the bearings to run on. This set fits a range of vehicles, including models like the Pontiac Sunbird and Saturn Vue, among others.
