You must have gotten bearings from a defective batch. Porsche gets these bearings from ***, they are a quality manufacturer like NTN or Timken. A standard bearing like this has no reason not to last as long as the one they sell to Porsche. There are also Chineese replicas that are packaged and sold on brand name boxes, make sure the bearing shop is a good one.
I wondered at the time if I could have inadvertantly put some pressure on the inner race - which of course spells doom to a perfectly good bearing.

Just so happens, Harbor Freight is offering their 20 ton shop press for $150 (normally $250)! Sure, it's not the best quality press out there, but when you only use it handful of times a year, it should last a long time. Xmas came early for my home shop More info to come soon.

Used a 9/16" cheap socket to press out the bearing. Stephen, you weren't kidding! I used a 20 ton press, and cranked on the hydraulic jack a lot more than I expected! Photos of measurements also below.
Exactly! Nice job finding that link.
Now, to source the bearings...

UPDATE: Purchased two bearings from VXB.com -- http://www.vxb.com/page/bearings/PROD/Kit7187. Pressed them into OEM deflection pulleys today. Used a Craftsman 1" socket to make contact with the outer race.

I am doing the same thing right now while my engine is out. Use a little heat before pressing the old ones out. Much, much easier. Also I think the 3202-2RS spec is closer. Im checking with our local *** bearing dist. Monday.

Met with the local *** dist. today. He measured the old bearing right in front of me and sold me an MRC brand bearing that is made in America. He said it was the same or better than the ***. He said the *** are harder to get and usually not in stock. The bad news is that at @$50 each, you can almost get the new Porsche ones.

This was just a local bearing supply store right?
I also checked with Boca but theirs was made in China. The MRC brand bearing is indeed stamped "USA" so they should be fine. They also sell Timken so I bet you could get the exact IMSB that LNE uses for their kits.
