Old thread but for future search hits:

That bearing is 52x30x22 - inner diameter is 30mm, outer diameter is 52mm and width is 22mm.

You will not find it at the normal national bearing supply places as I checked. I got a replacement from my local Auto A/C specialist shop. Cost is around $25. I see they were offered on Ebay as well.

Here are some numbers I had noted that I think might be the correct bearings.

My supplier told me that the nose hub can get worn if that bad bearing is left too long since the bearing is not on the same plane as the drive belt. (He said Toyota later changed this and went with a 6 grove pulley as well).


If the nose hub gets worn, the pulley will wobble and never be straight. A replacement compressor nose is available and he keeps them in stock just for the Camry's.



Replacing my bearing fixed the noise I was getting from the A/C and I was happy to find that I didn't have any major wear to the nose hub. If you have noise (the bearing going bad) in that pulley, waiting too long until it to damages the hub will be much more costly.



I was just barely able to get the old pulley off by using a clutch holding tool and a puller. Don't try this without having both of these tools. I was lucky and the outer plate came off like it should (by hand - some are going to be corroded on and you will never get it off while still on the car). The pulley is a very tight fit on the nose hub and will require the puller.



It was VERY tight working on this in the engine bay but I was just able to position the compressor to remove the pulley without removing the lower coolant hose. I put some scratches on my inner fender area so now I would recommend removing the lower coolant hose if you are going to do this job since I can see now, with hindsight, that it will make it MUCH easier.


I cleaned everything up well (nose hub!) and levered the pulley (with the new bearing) part of the way back on with a small section of board – using the fender to lever against. (I then had to resort to use a small length of a wooden dowel to hammer on/against the pulley a few times for the last 1/2 to get it fully on.)



The snap ring then went on easily enough, followed by one or more of the small spacing washers (for the clutch gap), and finally the 10mm bolt to secure the outer face plate.



Important note: There is a dust shield that goes on one side of the bearing. Note it before and when you remove the old bearing since it is important that it be replaced. I paid extra for the A/C shop to press in my new bearing and they put it on correctly and told me this. If I had not had them do the job I wouldn't have known this and probably would have just tossed that part aside since I didn't notice or understand why or how it was positioned because you don't get a good look at it until after the old bearing is out.



Watch for that dust shield if you are pressing out the old bearing so you can install it back the same way.
