What is the purpose of main bearings?

Main bearings sit between the crankshaft and the engine block. Their primary job is to support the crankshaft, allowing it to rotate smoothly while maintaining proper oil clearance and oil pressure.

Does this set include all the bearings needed for an engine rebuild?

This set specifically includes the main bearings for the crankshaft. You will likely need to purchase connecting rod bearings separately, depending on your engine's specific requirements and the scope of your rebuild.

Are these bearings available in different sizes?

This particular part number, MS704P, is for standard size bearings. If your crankshaft has been machined undersize due to wear or damage, you would need to check for specific undersize bearing part numbers from Clevite.
