I got mine from MSC industrial supply. About $12 for the set of two.
They were made in the orient, however, for 3450 RPM I think that is
ok. I don't think I would ever put a chinese bearing in a shaper
spindle cartridge. You can pay more for domestics if you like.
I miked mine and found the correct size and seal in the catalog but if
you live in a town with an industrial supply house, you can take the
old ones in and have them cross matched by the numbers on the
bearings. I suspect that will cost less than going directly to a
Marathon Electric repair shop. I'm assuming your motor is a Marathon,
based on the age you stated.
If you get stuck in the middle of it, email me, I'll try to help you
out.

Yes, I replaced the motor and bearings in my 15 yr old unisaw couple of
years ago,,, No real problems, though the arbor threads got a little
distorted and I had to re-thread it some. Used a hydraulic press and just
shoved em on...

Yes, it is not that hard to do if you are careful.
Disconnect all connections in the power connection box on the motor
case
Disconnect wiring to the capacitors and remove them. Discharge the
capacitors first so you don't get a pop.
Remove the bell housing and fan. newer models have a snap pin holding
the fan on.
Take some fingernail polish or paint and put a dab on the case to
endcap joint at several spots so you can put it back in perfect
alignment, although it probably isn't that important.
remove the nuts holding the tie rods on.
carefully pry off the end caps.
I cant remember if you have to disconnect the centrifugal switch. I
was taking mine down further so I had to. You may have to to get to
the fan end bearing.
Bearings are slip fit to the end cap (OD) and press fit to the shaft
(ID) so you need a small gear puller to get the old ones off.
Put on new bearings. I tapped them on with a wooden dowel that had a
hole cut in the center to clear the shaft.
reassemble in reverse order.
Good idea to take digital pictures of your connections as you go so
that you can get it back like it was. When you assemble the end caps,
make sure you spin it to ascertain that you did not inadvertantly
position a wire that is in contact with the cent. switch.
good luck
