worn motor bearings, 1972 DeWalt Radial Arm Saw, bought new, steadily used for 48 years.

The first problem was that the bearing sent were not correct. Outer diameter was 35 mm, rather than 40 mm required. My Black and Decker saw was model # 7740/3421 Type 2. The bearing required was 17mm id, 40mm OD, 12 mm thickness. The bearings sent had a 35 mm OD. Strangely I bought the correct bearings from Amazon, 2 for $21. At least two other parts houses had the correct size identified.
Replacement of these bearings is difficult, required pressing the old bearings off and pressing new ones on. It is not a hard interference fit, but challenging, because of access and difficulty find a sufficiently strong spot to set the puller. the interference fit to shaft (ID) requires hundreds of lbs force but the outside fit to housing is very easy, 50#. The major problem was tying to get the forward and rear section of the motor body apart. There are two roughly 1/4" alignment steel pins hard driven into the aluminum castings and these had corroded offering tremendous resistance to movement. I used JD weld metal filled epoxy to put 1/4" x 1/2" x 1" tabs on the side of the housing. I drilled the tabs and installed short 1/4 x 21 cap screws to provide a grip for the gear puller. After what seemed like a very high force applied, they broke loose and I managed to get the rotor out. I used a rubber hammer to drive the rotor shaft out of the forward housing and a gear puller to pull off the rear bearing. The rear bearing shaft was carefully cleaned, was lubricated with an anti corrosion spray and the bearing driven on using a deep 3/8 drive socket. The forward bearing was, after careful cleaning of the socket, tapped into place with a piece of 1/2" high density poly and a rubber hammer. The rotor and shaft were then pushed through the forward bearing and pulled into place with a pipe spacer and the reverse threaded brass nut that hold the blade on. The rear section bearing fits fairly easily into rear housing and is tapped home with the guidance pins and rubber hammer. The long bolts are put in place to hole the motor together. Hopefully these bearings will last another 50 years, much longer than I will.
I did not return the incorrect bearings because they are worth $8 total and postage would be $12. The correct original bearing number for front and back is 330003-16. The type 1 motor had different bearing fore and aft and perhaps this was the issue.
I would suggest on items like bearings, it would save a lot of time if you provided the three dimensions. Of all the websites I looked at, only one provided the dimensions. I then had to trace two more current replacement model bearings and found the right ones by typing in the current model number on Amazon. I probably had 12 man hours in finding the right bearings. Prices on the web varied from $1.86 to $27 for what appeared to be the exact same bearing.

took the sander apart to get to both bearings on the motor. used a puller to pull bearings off shaft. put it back together. The reason I fixed this sander is its one of the old 1/2 sheet vibrator sanders that you can't buy anymore, but I use them a lot for my wood working projects.
