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

The +0.50mm sizing indicates that these bearings are designed for a crankshaft that has been machined down by 0.50mm. This is typically done during an engine rebuild to address wear or imperfections on the original crankshaft journals.

What is the construction of these main bearings?

These main bearings are constructed using a bimetal design with an aluminum base. This type of construction is known for its good thermal properties and wear resistance, helping to ensure smooth crankshaft operation.

Are these bearings a direct replacement for all Mazda MPV models?

These bearings are specifically designed for the 1989-1998 Mazda MPV and certain other Mazda engine codes (JE06, JE27, JE39, JE48). Always confirm your specific engine code and vehicle fitment before purchasing.
