What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are slightly larger than standard. This is typically used when the crankshaft journals have been machined down (ground undersize) to repair wear or damage. These bearings then bring the connecting rod assembly back to the correct operating clearance.

What is the bimetal construction with an aluminum base?

This refers to the material composition of the bearing surface. A bimetal bearing uses multiple layers of metal, with a strong aluminum alloy as the primary base layer. This design offers good load-carrying capacity and conformability, which is important for engine bearings.

Are these bearings sold individually or as a set?

This product is a connecting rod bearing set, meaning it includes all the necessary bearings for the connecting rods on your specified Mazda engine. You will receive multiple bearings, enough to service all connecting rods in the engine.

Product Details

Built with a bimetal construction using an aluminum base, these King Engine Bearings connecting rod bearings are specifically sized at +1.0mm, making them a solid choice for engine rebuilds on your Mazda VC, UB, NA, or VA engine. This set is designed to fit your 1972-1976 Mazda B1600, ensuring proper clearance and oil film support for the connecting rods during operation.

The bimetal design offers a good balance of strength and conformability, which helps these bearings handle the loads within the engine while still adapting to the crankshaft's surface. Using a +1.0mm undersize bearing like this is common when the crankshaft journals have been machined to correct for wear or damage, allowing you to bring the engine back within proper tolerances. King Engine Bearings is a well-known name in engine components, and this set is made to meet the demands of a rebuilt engine.
