Plus at if you idle alot in traffic that is hrs at 0 mileage, heat and contamination also plays a role. You do the math on the way you drive, but the average mileage is approx 125,000 before the bearing is completely toast. YMMV.

I believe the rotating speed of the IMS is less than engine speed. I have not checked the gear ratios myself, but have heard that it was about 2/3 of engine speed. So, the average IMS bearing speed should be something like 2000 RPM, which should give a pretty long L10 life.
Unfortunately, it seems there are other factors the math does not account for. From what I have read the anecdotal info seems to imply that "generally" if they make it past 45,000 miles they are "probably" good for 100K miles, but I would not push my luck beyond that.
