Fitting bearing for case

[mmocfd1b0ab5a3]

I don't know if this is right section to post but I'm building case and I'll install one or two ball bearings on top of case. I have never made bearing housing for aluminium myself so what is good fit for 40mm or 47mm outer diameter bearing when axial load is low? If I want that the bearing can't be displaced without raw power will H7 (+0.025) do the job or do I really need interference fit?

Going to assume you are in the wrong section since i can not for the life of me figure out why Bearings and axel load would matter in a computer forum.
