Bearings issues

[captain harlock]

I've got some 16x5 ceramic bearings which have a narrower outer frame than the ones the UE 16x5x6 have.

That's the only problem my ceramics have. BUT THEY DONT SNUG IN THE RACER X KNUCKLES BECAUSE THEIR OUTER FRAME IS NARROW.
Do you guys know of a way to take the bearing apart so that I can put the ceramic balls in the race of the UE cage and thus it can snug in the knuckles?

Or, if there is a way to fill up the space between the outer frame of the ceramic bearing and the hole of the knuckle via a certain type of spacer or anything?

Please help me as much as you can.

Thanks,
