Unsure what you posted , try google speedy sleeve and see if that's what you need?

Its basically a serrated shim sized to specific bearings, you bore the housing oversize- for a 6204 the size is 48.86-48.97mm then slide it into position by overlapping the ends.
From what I can see it would work behind a circlip quite well, fitting the bearing appears to press the highpoints flat locking things up. Thats probably the best way I can think to explain it

Ok sounds alot like a speedy sleeve which you can buy at any bearing shop should work fine.

I thought speedy sleeves were only for shafts

Shafts are normally built up and re machined , Inside of housings you would bore it and fit a sleeve , You can sleeve a shaft thou.
