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

The +0.50mm sizing indicates that these bearings are intended for use when the engine's crankshaft has been machined down by 0.50mm. This allows for proper oil clearance and a snug fit on a reconditioned crankshaft.

What is the bimetal construction and why is it used?

Bimetal construction uses two different metal layers. In this case, a strengthened aluminum alloy is used for its good wear resistance and ability to conform to the crankshaft, which is essential for proper bearing function and longevity.

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 installation in the specified engine.

About this part

Product Details

What you get here is a set of main bearings, sized 0.50mm over, from King Engine Bearings. These are built for specific Audi engines like the CDAA, CDHA, CDHB, and CDAB, and also fit a range of Volkswagen models including the Beetle, Golf R, Jetta, and Passat. These bearings are made from a strengthened aluminum bimetal material, which is a solid choice for main bearings because it offers good wear resistance and conformability to the crankshaft.

When you're rebuilding an engine, especially if you're dealing with a worn crankshaft that needs to be machined, using the correct undersize or oversize bearings is crucial for proper oil clearance. These King bearings are made to King's specifications for bimetal construction, meaning they have a strong aluminum alloy layer that handles the load and wear well. They're designed to fit right into the specified Audi and Volkswagen engines, making them a reliable option for your engine build.
