What does the 0.05mm undersize mean for these bearings?

The 0.05mm undersize indicates that these bearings are designed for a crankshaft that has been machined down by 0.05mm. This is a common practice during engine rebuilding when the original crankshaft journals have wear and need to be re-ground to a standard undersize.

What engines are these main bearings compatible with?

This specific main bearing set is designed for Audi and Volkswagen engines with the codes CFFA, CAYB, and CAYC. Always verify your engine code to ensure proper fitment.

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 installation.

About this part

Product Details

King Engine Bearings is known for making solid internal engine components. This main bearing set, part number MB5337MC0.5, is a good example of their focus on reliable engine parts. These bearings are specifically sized at 0.05 millimeters undersize, which is important when rebuilding or repairing an engine that has had its crankshaft ground down to match this size.

This set is designed for specific Audi and Volkswagen engines, including the CFFA, CAYB, and CAYC. When you're putting an engine back together, the main bearings are critical for supporting the crankshaft and ensuring it spins smoothly within the engine block. Using a well-made bearing set like this helps maintain proper oil clearance and reduces friction, which is key for engine longevity and performance.
