What does the +.025mm size mean for these bearings?

The +.025mm designation indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined down by .025mm to ensure a proper fit and oil clearance.

What is the PMaxBlack overlay?

PMaxBlack is a specialized overlay applied to the bearing surface. It's designed to enhance the bearing's ability to withstand higher loads without deforming or failing, which is important for performance applications.

What is the benefit of the Radialock feature?

Radialock is a design feature that helps the bearing achieve the correct 'crush height' when installed. Proper crush height is essential for the bearing to seat firmly in the housing and maintain adequate oil film thickness.
