Press Fit

[DELurker]

All of your bearing fit information (radial ball) can be found in the chart on page 131 at http://catalog.timken.com/WebProject...ookcode=eng11#, with the codes defined on pages 132-145.

If you can't make the holes to the specifications listed there, 0.001" undersized should work. I've found that Loctite Retaining Compound 641 works well in other applications, if you want to make the hole right at the bearing diameter.

As for press fits into thinner materials, I would recommend a flanged or snap-ring bearing with either retaining compound under the lip or 3 screws at 120-degree intervals.
