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

The +0.50mm sizing indicates that these bearings are 0.50mm larger in diameter than a standard-sized bearing. This size is typically used when the engine's crankshaft journals have been machined down (ground undersize) to remove wear or damage.

What is bimetal construction?

Bimetal construction means the bearing is made of two different metal layers. In this case, it has an aluminum base, which is known for its good load-carrying capabilities and compatibility with crankshafts.

What is the primary function of main bearings?

Main bearings support the crankshaft within the engine block. They maintain the correct oil clearance between the crankshaft and the block, allowing the crankshaft to rotate smoothly while handling the forces generated during combustion.

About this part

Product Details

King Engine Bearings is well-known for making solid engine bearings. If you're rebuilding the bottom end of your 1983-1997 Toyota Corolla with a 2A, 3A, or 4A engine, this main bearing set is what you'll need. These bearings are made with a bimetal construction, meaning they have an aluminum base, which helps them handle the loads inside your engine.

This particular set is sized at +0.50mm, which means they are 0.50mm larger than standard. This size is typically used when the crankshaft journals have been machined down to account for wear. Using the correct size bearing is crucial for proper oil clearance, which ensures your engine runs smoothly and lasts longer.
