Tensioner pulley bearings - source?

[alia176]

I'd like to replace both tensioner pulley bearings. The p/ns are:

PS tensioner: 6301DU2
A/C tensioner: 6202DU2

I know that Suparuparts has them for around $40 or so but I'd at least try to source just the sealed bearings. A search revealed that this has been discussed before but I didn't find any source. The nearest place is Motion Industries who has them for $17/each or so. Has anyone had any luck at the NAPA type places? I also found them on the 'net at A&W bearigs at a very low cost. Unfortunately, there's a min of $25 to purchase!

Removing the A/C pulley bearing was easy but the PS pulley required a little bit more work. I had to ground off the four pop rivets out of the pulley, remove the backing plate and then pop out the bearing. Makes me wonder why the PS pulley doesn't use a simple retaining clip like the A/C pulley!

Thanks for any info.
