Because it has "teeth" and the notch I don't think it's a bearing. Hard to get a good idea what it is because picture is blurry. Would help if you also had another picture that wasn't close so one could get the "big picture."

You might want to try the DIY discussion group, they probably would be interested and more knowledgeable.

I don't think that "part" is supposed to come off. I think it's just part of the outer shell that the shaft slips into and not a bearing. The shaft is held to the outer shell by a set screw making the shaft, outer shell and squirrel cage rotate as one piece.

I've taken cage shafts out before and it's no fun at all. Get some good penetrating oil like PB Blaster and spray it a few times then start pounding. Those shafts like to rust in place making them very hard to get out.

its most likely a split ring since you see a notch in it get a set of pliars on each side of the notch and pull don't worry about saving it either looks like its toast

guys & gals, this is rather obvious----the flux capacitor on the pulley has failed, causing the entire evaporative cooler to sieze!

It looks like a cheap keyway bushing. Probably a press fit thats corroded. Try penetrating oil. If that doesn't work try heating the pulley (not the shft) with a torch. You might try a bearing puller, but the shaft may be too thin.
