What does the 0.75mm size mean for these bearings?

The 0.75mm designation indicates that these bearings are undersized by 0.75mm. They are intended for use when the engine's crankshaft has been machined down by 0.75mm to correct for wear or damage. This ensures proper oil clearance and performance after the crankshaft has been reconditioned.

What is the construction of these main bearings?

These main bearings utilize a bimetal construction, which includes an aluminum base. This type of bearing material is well-known for its good performance characteristics in engine applications.

Are these bearings a direct replacement for standard size bearings?

No, these are specifically 0.75mm undersize bearings. They are intended for use with a crankshaft that has been machined to match this undersize. Standard size bearings would be a different part number.
