What does the 0.25mm size mean for these bearings?

The 0.25mm designation indicates these bearings are undersized by 0.25mm. This is used when the crankshaft journals have been machined down by 0.25mm to remove wear or damage, and these bearings will bring the clearance back to the correct specification.

What kind of engine loads are these bearings best suited for?

These bearings feature a lead-free composite material that is ideal for engines experiencing low to medium loads. They are a good choice for standard rebuilds where extreme performance isn't the primary goal.

Are these bearings environmentally safe?

Yes, these bearings are made with a lead-free composite material, making them an environmentally safe option.
