What does the '+0.75mm' mean for these bearings?

The '+0.75mm' indicates that these bearings are 0.75 millimeters larger in diameter than standard size. This is used when the crankshaft journals have been machined down (ground undersize) and then built back up or replaced to a specific oversize dimension.

What are bimetal bearings?

Bimetal bearings, like these, typically feature a steel backing for strength and an aluminum-based overlay for excellent conformability and embeddability. This construction helps them handle loads effectively while maintaining good contact with the crankshaft.

Product Details

This set includes the connecting rod bearings you need for your engine rebuild. Specifically, these are bimetal bearings with an aluminum base, designed to fit Mazda MA and VB engine codes, which are found in vehicles like the 1972-1979 Ford Courier and various Mazda models from the 1970s and early 1980s.

These bearings are built to precise specifications to ensure proper oil clearance and load distribution within your engine. They are manufactured to be 0.75mm oversize, which is important if you are reconditioning your crankshaft journals to that specific size. Using the correct size bearings is critical for maintaining oil pressure and protecting your engine's rotating assembly from wear.
