No one said it was the controlling issue. It's just a factor.
Don't see why you don't consider replacing bearings to be a suitable
address of the problem. They are meant to be replaced, after all...

If they are sleeve bearings, NBD.

If they are ball bearings, you really need an arbor press to avoid
brinelling
the bearings during installation.

$10 for a box fan is a far more simple solution.


Can you really get anything from Grainger for $10? As for the bearings -
they are very easy to press in with a hammer with no problems. Many of us
have done that kind of thing for decades, with no problems. I'm not
talking about simply mashing them in - but it is not rocket science to
seat a bearing.

But, if a hammer seems too crude, you can make a cheap press at the hardware
store.
Buy two short ones of these, one that's a little larger than the outer
flange of the bearing, one that maches the outer flange:

Buy a piece of this that is the largest size that will fit through the
bearing:

Buy a couple of nuts and washers that fit the all-thread.
To remove the old bearing, fit the big nipple over the bearing, slide the
all-thread through, put on nuts and washers, tighten nuts.
To install the new bearing, put the big nipple against the hole that the
bearing will go in, slide the all-thread through, slide the bearing and the
small nipple on, put on nuts and washers, tighten nuts. Get a satisfied
feeling when the bearing seats.
