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

The +0.50mm sizing means these bearings are designed to be used when the crankshaft journals have been machined down by 0.50mm. This is a common practice during engine rebuilding to achieve proper oil clearance with a worn or machined crankshaft.

What is the primary function of main bearings?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining the correct oil clearance, which is vital for lubrication and preventing metal-on-metal contact.

Are these bearings sold individually or as a set?

This product is a set of main bearings. It includes all the necessary main bearings for the specified Audi Cepa or Cepb engine application.
