still use it. I have kept it maintained by the original instructions
that came with the saw when my father in law bought it.
In those instruction its says the saw arbor bearing are "packed at the
factory with the proper lubrication and require no additional lubrication"
After 40 years should these bearings be lubricated? And more importantly
HOW?

Bearings of that kind are generally sealed. There is no way of greasing them
except by taking them apart. If you do this, there is no way of putting them
back together. Run them till they die then replace them.

S&R has used a water pump bearing in those saws since they were
designed.
(I had a late '40s unit which used a W/P brg)
As such, it is a sealed, non re-greaseable, bearing unit.
As CW suggests, run it till it dies, then replace.

Ditto to both above suggestions. Remember, some of the equipment
built during that era were made hell for stout. They hadn't quite
figured out planned obsolescence yet.
Example; When we sold my mother-in-law's house five years ago her
1955 vintage chest-type freezer was still churning away in the
UNHEATED detached garage. Talked to the new occupant a few weeks ago
and it is still running. "No way in hell I'm gonna move that thing an
inch."

as long as possible. But since I am not a professional, my use may never
require replacing the bearing based on what you are telling me.

My only backup suggestion would be to spend a little time finding a
source for the bearing, or arbor assembly as the case might be, and
save the source. If it isn't horribly expensive, maybe even buy it
and put it aside (in one of those "safe places" that always
disappear). A year or so I would have told you that Sears/Craftsman
maintained a good parts supply for old tools. Not necessarily true
any more. I recently bought an 80's vintage dovetail jig set in an
estate auction thinking the manual would be readily available. I got
on Sears support site and the manual, and about 1/2 the parts are
discontinued. That doesn't mean you cannot find the parts but it
might take a little more searching.
As far as that goes the bearing might be available from an industrial
supply source.

I have the original Manual for 315.25720 Sears jig.
It is basically a upside down piece of channel with the dovetail
template on top and a clamp on the side.
I have been looking for an excuse to scan it into my computer.
(I am slow getting all of my "toy" manuals on line in PDF files. )

You mean I'm not the only one whose safe places to save things sometimes
warp into an alternate dimension? The only way I seem able to reliably find
stuff is if it's in a big plastic bin with a label on the front, and even
then the bins occasionally hide from me....

My suggestion on a 40 year old saw would be to go ahead and tear down
the arbor and replace the bearings. Have a look over at OWWM.com and
on the OWWM.org forum. You will probably find a lot of info on
rebuilding a saw of that vintage.
Lifetime bearings only last as long as the lubricant and then other
things (like your arbor) get worn out. You can probably find
replacement bearings. It's doubtful you will find a new arbor
although a used replacement is a possibility.

It's a water pump bearing.
Translation:
Outer race, arbor and two (2) rows of ball races are an integral unit.
You replace the whole thing as a unit.
The ends of the arbor are machined as req'd for the application.

That's not bad advice all by itself, but I'll add a bit to it. 40 years on
a table saw is not the same as 40 years on something like a car. A table
saw is largely an occasionally use device. 40 years can be a moment in time
for that saw. I have a 50 year old Craftsman table saw that still has its
original bearings in it. Running just fine. It clearly has not seen daily
commercial use, thus the extended life of these bearings, but that's
probably true of more saws than not. I would not worry about it until it
starts to make noise. What's to risk?

Remove the belt, put a blade on the arbor and raise it; try to
wiggle the blade. Spin it, listen for rattle or scrape sounds.
If it's moving normally, use the saw. If the blade wobbles,
the arbor may be bent and need replacement, and you might as
well (they're cheap) put in new bearings if you are disassembling
it anyhow. The bearings are sealed ball bearings, two of 'em,
and don't have to come from the manufacturer. Measure and buy
replacements anywhere mechanics are served.

It usually happens when you are building a big project. :-)
But I too, would wait til it ground to a sudden stop, or more smoke
emerged from it than the wood being cut with a dull blade..

My inlaws built a new home in '52 and bought new appliances. Down the road
they bought a new fridge and put the old one in the basement. since then
they have replaced the fridge in the kitchen a couple more times. Mean while
the old one in the basement is still keeping the beer cold
