I say bearings. If your belt tension was too tight you can ruin them very quickly. I can’t tell how that motor is assembled but if you take the four nuts off the end and remove the end cap you should be able to pull things out You may have to drive the bearings out by getting a piece of pvc pipe the same size as the OUTER RACE ONLY and use it to drive out the bearings. Go to any motor repair shop and they will match up what you have. Ask for Japanese bearings, not Chinese ones. I’ve taken a few motors apart, it’s not that hard.

One thing I want to point out though – that motor is incorrect for that saw. It looks like a blower motor judging from the mount (is it 1750 or 3500 rpm). It should have a start capacitor on top of the motor housing and a thermal reset switch on the end. You may be better off buying an actual saw motor.
