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

The +0.50mm sizing indicates that these bearings are designed for a crankshaft where the main journals have been machined down by 0.50mm. This is a common practice during engine rebuilds to ensure proper oil clearance when the original journals are worn or damaged.

Are these bearings a direct replacement for stock main bearings?

No, these bearings are specifically sized at +0.50mm. They are intended for use only when the engine's main crankshaft journals have been machined to this specific undersize. Always confirm your engine's journal size before ordering bearings.

What is the primary function of main bearings?

Main bearings sit between the engine block and the crankshaft. They support the crankshaft, allowing it to rotate smoothly while handling the immense forces generated during combustion. They also help maintain the critical oil clearance needed for lubrication and cooling.

About this part

Product Details

This is a main bearing set from King Engine Bearings, specifically for VW EA888 Gen III engines. These bearings are sized at +0.50mm, meaning they are intended for use when the crankshaft journals have been machined down by 0.50mm during an engine rebuild. Main bearings are crucial components that support the crankshaft within the engine block, allowing it to rotate smoothly while handling significant loads.

King Engine Bearings is a well-known name in engine components, and this set is built to support the demanding environment inside an EA888 Gen III engine. The +0.50mm sizing is important; using the correct undersize or oversize bearing is essential for achieving the proper oil clearance, which is critical for engine longevity and performance. If your engine build requires machining the main journals, this set ensures you have the correct bearings to match.
