I looked at your photos but no clue there. You definitely do not want to put any oil in the electrical connection box you show. I think you are going to have to look at the areas around the bearings. If there are no grease fittings or oil tubes, you may have to just squirt some oil at the shaft where it disappears into the shell and hope.

Thanks, wondering if that whole cage needs to come off? It’s on a millrite mill.

I would not use oil. First I would get rid of the power cable. If you cut back the 3 wires it may not be good. Often the exposed wires with hardened/cracked insulation reflect bad sections in the jacketed section.

Power cord already replaced, thanks. Agree, it was a mess.
Based on the age of the machine, i would pull the motor and replace the bearings, generally by the time rolling element bearings get bad lube won't help them.
If they jam in use they will damage the motor, right now it should be a quick and easy fix for just the cost of a couple of cheap bearings, continue to use it and the damage will be a lot more involved to fix.
