King Engine Bearings Datsun A12/(Size +0.50mm) Main Bearing Set

King Engine Bearings is well-known for making solid engine components, and this main bearing set is no exception. If you're rebuilding the bottom end of a Datsun A12 engine, these main bearings are a critical part of getting it back in running order. They are designed to provide the correct oil clearance between the crankshaft and the engine block, which is essential for proper lubrication and engine longevity.

This particular set is a +0.50mm size, meaning it's intended for use when the crankshaft journals have been machined down by 0.50mm. The bearings themselves are constructed with a bimetal design, using an aluminum base. This construction is common in modern bearings for its good wear characteristics and ability to handle the loads within an engine. They fit a range of Datsun and Nissan vehicles, including models like the Nissan 1200, 210, and B210.
