It's not usually a good idea to press-fit a ball bearing at all. It can change the fit/preload of the balls. You should use the recommended housing bore and shaft sizes and tolerances found in the bearing catalog. The proper fit depends on whether the housing or bearing (or both) are the rotating or stationary member.
A frictionless bearing can be retained using a variety of standard methods, like a retaining ring & pre-load washer, a bearing cap, a bearing locknut, etc. As a last resort, I would use Loctite before I would press fit a ball bearing.
A good resource for bearing mounting methods is an old New Departure Handbook. You can usually find them on Ebay. Here's one:

Corky7 An old "Rule of Thumb" to which my workshop always worked was to have an interference fit of one thou per inch of diameter - - - so for your situation, you should have .0005. In a worst case of possible tolerances you would get nearly twice that Obviously your job is not important else the designer would have sorted out these queries and you wouldnt be asking for guidance
I'd be inclined just to push it in with whatever means you have, including a block of wood plus hammer. if it feels wrong, take it out again and try another bearing with different tolerance.

Here are some good links:
I would not worry about calculating the force since most presses/ bearing mounting tools will have plenty of force to mount a bearing this small.
The most important thing is to put uniform force all around the ring and never use a hammer directly on the bearing. Press on the outer ring to mount in the housing and press the inner ring to mount on the shaft.
Good luck.
