Somewhat of an odd question:
I have a BB386 EVO frame that uses a PF30 Bottom Bracket.
I an in search of the dimensions of the bearings used in PF30 cups.

ID: 30mm (obviously)
OD: diameter of outer bearing race.
Width: inboard to outboard thickness.

I am not interested in the OD of the cups or BB shell, (I know this is 46mm)

Are the bearings pressed into the PF30 cups the same size as standard BB30 bearings? I believe both are 6806 bearings.

I feel like I have seen this info somewhere before but I can't seem to find it again.

Bearings ID will be 30mm if you want bearings for 30mm crank(386), 24mm if you want bearings for 24mm (Shimano crank). OD of bearings can vary from manufacturer to manufacturer- dpends on cups design.

I understand you want leave cups and replace bearings only (?). Best is to tap off of the frame and take measurements... .

I can be wrong, and have plenty of examples for that ;)

I have an FSA PF30 beside me as I type. Bearings are 618062RS, 30x42x7mm.

I'm fairly sure most makes of PF30 use this bearing, or the 71806 angular contact variant.

Your Google Foo is very weak: 30mm ID x 42mm OD x 7mm
