For any that may be interested, a bit more from the NSK manual:
For a rigid shaft or housing, the bearing rings expand/contract 70% to 90% of any interfernce fit.
For angular contact ball races our sizes CN (normal) grade the unmounted axial cleance is 40 to 60 microns, about .0015 to .0025 inch. This is decreased by any interference fit.
I dunno how the original Seven ac bearings matched but in the interest of the lip I am a little sceptical of assembled preload. (Adopted in my car but had a steel housing!)
