Product Details

This is a main bearing set from King Engine Bearings, part number MB572AM1.5. These bearings are designed for a range of Mazda engines, including models like the 626 and B1600, as well as the Ford Courier. They are built with a bimetal construction, meaning they have an aluminum base, which is a common and reliable material for engine bearings. This set is sized at +0.50mm, indicating they are intended for engines where the crankshaft journals have been machined down by 0.50mm during a rebuild.

King Engine Bearings uses a bimetal construction for these main bearings, which is a solid choice for many applications. The aluminum base offers good compatibility with crankshafts and helps manage heat. This set is specifically sized at +0.50mm, meaning it's meant for engines that have had their main journals ground down by that amount. Using the correct undersize bearing is crucial for ensuring proper oil clearance and engine longevity after a crankshaft has been reconditioned.
