Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

In this thread piper6909 refers to the NSK BD20-17 available from 123bearings as a replacement for the original dual row IMSB.

Has anyone actually tried this bearing? I just got a quote of $113.51 US. They are located in France.
I am again pondering the IMSB question for my 2000 Boxster's original engine. The factory bearing seems to be OK so I may just leave it (as I have done in 2 other engines), but it would be easier to change it with the engine out, which it will be for awhile.
I will NOT be using any of the LN kits... too pricey for a 20 year old car.
The Fvd Brombacher kit at $395 US looks interesting, but a new bearing for about $200 all in would be better... for me.
Sure wish Ben Burner would come back with a report on the custom ceramic bearing he installed. Imo000 over on rennlist tried another ceramic (from Boca?) and it did not end well.
I think this is the same exact bearing that was built into these cars in the factory, so it`s proven to be good since in most cars it lasts way over 100k miles. In general, I don`t see the advantage of the ceramic hybrid bearing over the original steel ball dual row for this application. When I rebuilt my engine I went with a roller bearing + ball bearing combo, but I might replace it to one like this when I decide to sell the car, as the bearing I used is unique and is not from a reputable source and buyers don`t like that.
I recently read your entire thread in the Show and Tell Gallery and was struck by your unique approach to the IMSB challenge. Impressive, both your bearing solution and the entire thread.
If I do use this bearing the next question in my mind is whether to remove the bearing seal at installation time and make it an oil lubed bearing from the beginning. The three IMSBs that I have looked at were all practically greaseless at 90,000, 97,000 and 115.000 miles.
I think both configurations (opened/closed) should work. The closed version is proven to be lasting, see your examples. But I don`t see why the opened version should not last just as long...
I am in the exact same position. I removed the transmission, clutch, and flywheel on my 2001 Boxster S and I am staring at a dual row flange.
It does not make sense to spend LN kind of money on a 25 year old car, especially for a dual row. I am thinking about replacing it with an OEM replacement. NSK BD20-17 A DDUA17 NX01
What did you end up doing and did you remove the seals?
That is the bearing I used and yes I removed the external (rear) seal. The car has a few thousand kilometers on it with the new bearing and no problems.
This is my thread on replacing the bearing...
https://986forum.com/forums/performance-technical-chat/81929-my-ims-bearing-replacement-thread.html
Thanks! I think I’m going to do the same: new “oem” and pull the outer seal. Your thoughts in the thread capture mine as well. Has good longevity with the seals…but also the grease washes out any way.
Did your bearing clip/ring come out okay? Ike worried about damaging it during extract and then having to source one. I may rent the LN tools to help it come out smoothly
