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

The +0.50mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.50mm. This is typically done to remove wear or imperfections from the original crankshaft journals.

What is the pMax Black coating?

The pMax Black is a special overlay applied to these race bearings. It's designed to reduce friction and improve wear resistance, particularly during the engine's break-in period and under higher load conditions.

Are these bearings suitable for a stock engine rebuild?

While these are race bearings with advanced coatings, they are intended for engines that have had their crankshaft journals machined to a +0.50mm size. If your crankshaft is still at standard size, you would need a different bearing set.

About this part

Product Details

If you're rebuilding the bottom end of your Nissan CA16DET, CA18DET, or CA20ET engine, a fresh set of main bearings is crucial. These King Engine Bearings are specifically designed for these engines and come at a +0.50mm size, meaning they're intended for crankshafts that have been machined down by 0.50mm to clean up wear.

These are Trimetal pMax Black race bearings. The pMax Black coating is a unique overlay that helps reduce friction and wear, especially during the critical break-in period. This construction is well-built for performance applications where oil pressure and bearing load are higher than stock.
