It is purely application dependent. Pleas have the habit of coming with some details. As you must be aware that along with this there are a few more recommended fits ?
Each are depending upon the type of housing, type of loading, type of load etc.
I will provide a link and you can use that.But please remember these are for general purpose applications and for specific applications these will likely to have quite significant changes.
In case of doubt, you can always refer the bearing manufacturers with the application, loading etc and ask for their recommendations.
The similar data is available in any of the bearing catalogues (in the beginning chapters - before the main catalogue starts) and also in the other major bearing mfr sites
FAG, TIMKEN have them. Others not checked but sure to have.
Once Again : Come with complete data if a help is required. Your question is just an extrapolation of what is the fit between hub and the shaft ? without any back ground.
