What does the 0.25 size mean for these bearings?

The 0.25 size indicates that these bearings are 0.25mm undersize. This means they are intended for use when the engine's crankshaft has been machined down by 0.25mm to correct for wear or damage during an engine rebuild.

What is the material of these bearings?

These bearings are made from a bi-metal aluminum composite material. This material is lead-free and considered environmentally safe, and it's well-suited for engines that don't experience extremely high loads.

Are these bearings suitable for all VG20E/VG20DET engines?

This specific bearing set is sized 0.25mm undersize, so it's intended for engines where the crankshaft has been machined to that size. Always confirm your engine's specifications and the condition of your crankshaft before ordering replacement bearings.
