What does the 0.25mm size mean for these bearings?

The 0.25mm designation indicates that these bearings are undersized. They are intended for use when the crankshaft journals have been machined down by 0.25mm to ensure a precise fit and proper oil clearance during an engine rebuild.

What is the overlay on these bearings?

The specialized overlay is a material applied to the bearing surface. It's designed to help the bearings withstand the high pressures and temperatures found in an operating engine, contributing to their longevity and performance.

Are these bearings suitable for a stock engine rebuild?

These bearings are sized 0.25mm undersize, meaning they are intended for a crankshaft that has been machined to that specific size. If your crankshaft is at standard size, you would need a standard-sized bearing set.
