I suppose that could work, you'd want to be careful sizing the o-ring or you could end up preloading the bearing more than desired. Another downside is the NR bearings do not come with any other features, such as polyamide cages, something I decided to go with this rebuild.
I used red loctite the last rebuild without issue but I'll be following LC's lead with the 610 product this time around.

I would suggest you use Loctite 620. It retains full strength at the working temperatures found in our engines.
Also it has 1 hour curing time so you won't be in such a hurry when assembling.
