Those look dangerous! I'd replace them and the saw blade. No, 3 in 1 oil isn't for bearings, the bearings were factory sealed greased bearings, if they're noisy they need to be replaced too.

The bearings aren't noisy the shaft just doesn't turn very easily.

Those are probably just chips on the wheels but it's not worth taking a chance. They have been impacted and could have fractures. Chunks coming off at that RPM is not a good thing!

The bearings aren't noisy the shaft just doesn't turn very easily. If the bearings are partially seized you still need to replace them. Most older machines need new bearings. Like I said, the original bearings are greased and sealed from the factory and are not oilable. Shaft should spin easily with motor belt disconnected, if it doesn't new bearings are in order. You can get new bearings from Grainger. I also wouldn't use new SC wheels, I'd get with the times and use diamond wheels.
