I have a 2014 Explorer Limited with a rattle noise on the AC compressor. AC works fine, but I'm worried it will eventually seize up and screw something up bad, like the whole compressor or even burn off the belt while driving.

I took off the belt and while the pulley spins freely, I can wobble it a few millimeters off the plane of the belt orientation.

I assume the bearing needs replacing, but also wonder if the shaft, which goes into the compressor and on which the whole clutch assembly secures to could also be the culprit(in which case would mean all new compressor).

Rough estimates:
New bearing $30
New clutch assembly $300(OEM) or ~$80(aftermarket)
New compressor $850(OEM)

Obviously, I'd like to just replace the bearing for starters, but don't think it alone is a Ford part.

Hardly the authority, but Amazon, with my year/model/engine info, suggests the following bearings:
35mm x 50mm x 20 mm
30mm x 52mm x 20 mm
30mm x 55mm x 20 mm
30mm x 47mm x 20 mm

Does anyone know a suitable replacement part number or item or even the correct size for the bearing?

Look on rockauto. They have only one bearing assembly ( motorcraft) listed. If you would had listed which engine, I could of given the part number.
Pretty easy repair. ( " I can wobble it a few millimeters off the plane of the belt orientation".) Your bearing went bad.

Thanks Pete, it's a 3.5L v6 (no turbo), but not seeing the bearing specifically by itself. I've hit a few AC compressor resellers that will take my VIN and display the bearing for $50 but won't give me the size so I can search around more lol
Also getting a bit wigged out how hard this is to find and don't want to take it apart to find the bearing I got in the mail is wrong that I'm about to just buy the whole damn clutch assembly and call it a day!

Try calling a ford dealership part counter. Maybe there is a break down of just the bearing.
try Ford part direct. Email sunrise ford. I uses too call them and get part number.
Century air in az might has a bearing.
The is high.
You can buy a compressor from rock auto for $200 and remove clutch assembly and install it on your car.
On older vehicles, you can only get the whole assembly. You're car is new.

Is this the compressor you are talking about?

Thanks to both Petes!

The part I needed is *just* the bearing inside 19D786, not the whole compressor(entire picture) or even all of 19D786, which includes the pulley, bearing, coil(aka "stater") as well as the shims needed to align the new pulley with the rest of the belt drive(water pump, alternator, etc.)
I took one of the Pete's advice and called around. Found a shop that just rebuilds/repairs/installs car AC compressors. They agreed to sell me just the bearing. When I went to get it, the counter guy's English was better than my Spanish, he tried to explain there are two possible bearing fitments. The bearing he sold me($35) was, in his experience, the most likely to fit as it is the one found in the majority of 2014 OEM Explorer 3.5L v6 non-turbo compressors

35 mm x 52 mm wide x 20 mm

To put that into perspective(I am not a mechanic)
35 mm is the diameter between the inside edges of the bearing
52 mm is the diameter between the outside edges of the bearing
20 mm is the height of the bearing when it is laid on it's side flat

He said the next most likely fitment was 35 mm x 52 mm wide x 22 mm as some have a lip which extends 2 mm past the rest of the bearing(when laid on it's side). When I asked him why, he said Ford can do stuff like that sometimes.

He offered to replace my bearing(part+labor for $100) if I brought him my compressor, but I can't exactly just take out and hand over my compressor so I just bought the bearing and was on my way.

This morning I got the pulley puller borrowed from AutoZone and began to replace the bearing. I hoped to just take off the belt, unhook the electrical connector, unbolt the three bolts holding the compressor to the engine, lower it with the coolant lines still connected and then pull off the pulley and replace the bearing before putting it all back together. I got under the vehicle to feel out the bolts(2 of the 3 are easy, but third next to the electrical connector is essentially a blind feel) but before doing anything find I had rather underestimated the available slack in the AC coolant lines(basically, aluminum tubing). While I could get the securing bolts and electrical connector off, I seriously doubt there is enough slack in the lines to lower it without pinching, cracking, etc. the lines and getting coolant everywhere. I don't have the equipment to deal with draining the lines properly so I've decided to just let the pro handle it(this is literally all they do, JUST AC compressor work).
