How easy or hard is it to change a bearing in an GE ceiling fan?

Not too hard. It can even be done with the fan hung, but best to do on a work bench. 
For a 1920’s GE:

Remove power. 

Unbolt the blades from the hub. Tag their positions so each blade can go back in the same position for balance. 

Lower the canopy, disconnect the wires, and take the fan down. 

If the switch is present in the oil cup, take it off.

There is a secret setscrew in the side of the oil cup that locks the oil cup to the axle. Loosen it. 

If there is an axle nut inside the oil cup, remove it. It might be backwards threads. 

Unscrew the oil cup and remove it. You can:

    Grab the cup with a strap wrench, or

    Remove the plugs where lights would mount, stick a long screwdriver through the holes and use as a lever, or

    Clamp the oil cup in a vise and grab the fan body and unscrew it

The ball thrust bearing is in the bottom of the oil cup. There will also be a felt washer or two. 

Clean and inspect the bearing. If it has no damage and is smooth, reuse it. Otherwise, buy a new one on Amazon or at a bearing supply store. 

The new bearing might be thinner, so you may need to add additional steel or felt washers.

Some bearings have a slightly smaller inside diameter on one race. This race goes on top. If too tight, grind it larger or get a different bearing. 

Remove the fan bottom cover and remove the rotor. 

Clean old oil out of the rotor’s top reservoir, clean out the drain back oil passages, and clean the spiral groove where the axle rides. 

Before reassembly, coat the axle threads with a sealant to keep the oil from leaking out. I use Yamabond 4.
