I believe those are sort of a hybrid between cartridge bearings and cup and cone. I'm not sure but you may not be able to get the bearings out as there is some sort of race in there. Rather you would have to pull out the whole "cartridge".
I don't know much about them but I know some of those supurbe pro hubs had a unique bearing setup, and I think that's one of them. If you don't have luck here ask in the fixie forum.
The cones should be two piece items that CAN be pressed apart. If so, and you remove the cups in the hubshell, you can install #6001 sealed cartridge bearings like Mavic, Suntour XC, Sanshin, Specialized, etc.
You'd do this to fix the hub if you'd pitted a cone or cup and couldn't get a replacement part. Conventional cones will push the bearings out of their intended track in the cup, as the hub is almost a radial contact bearing hub, as opposed to the angular contact bearing used in most loose ball hubs.
