What does '0.010 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.010 inches smaller in diameter than a standard-size bearing. They are intended for use when the crankshaft journals have been machined down by 0.010 inches during an engine rebuild.

What is the CP coating on these bearings?

The CP (Coated Performance) coating is a special overlay applied to the bearing surface. It helps the bearings seat quickly onto the crankshaft and provides improved resistance to wear, which is particularly beneficial during the engine's break-in period.

What is the main function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining the correct oil clearance, which is essential for proper lubrication and oil pressure throughout the engine.
