which ims bearing upgrade

[Gelbster]

Sometimes the best(?) answer is to just follow what has worked best for others .
No need for DOF + Hybrid ceramic bearing. Splash is sufficient. If you wanted to experiment, you could buy a DOF kit and substitute a hybrid ceramic bearing for the generic steel bearing usually included.The generic bearing is only worth $5.
Nobody sells a full ceramic IMSB?

Is this what you mean? check size.

A bigger challenge may be to find an IMSB tool kit at a reasonable price that ships to Malta?

I was just curious as to why LN dont do their bearing fully ceramic,is it cause of cost,or is a hybrid ceramic the best way to go? Is it the cage or the balls themselves that will fail first in a hybrid ceramic bearing? Yes,thats the sight I will have to buy everything from, design 911 in the UK,including bearings. Nothing comes cheap, thats the problem,its gonna coast literally thousands to get this done,since shipping is quite expensive,and I'm going to be ordering clutch kit and flywheel as well, so that's why I want to spend wisely �� I think I get the impression that the majority here lean towards LN's bearings,right? Btw,how many cam covers will I need to replace on a 5 chain car, is it 2? And do you know the part number for the micro encapsulated bolts as well? Design 911 sell micro encapsulated bolts for clutch and flywheel,any idea I those fit the ims bearing flange?

A full ceramic bearing would cost around 3K per unit to have made. On top of that the compatibility between the ceramic balls and the hardened steel races is NOT an issue. The only time it becomes an issue is when debris contamination finds its way between these surfaces.

This will happen with any portion of the engine, not just the IMSB, the same things happens with cylinder and piston wear, and the list goes on.

Just ship your car to Flat 6 Innovations and have them do for you what they did for me and start enjoying that car and living life.

Just do it.

The sooner you do, the sooner you can sleep at night

That makes too much sense. Thats too easy.

Thats great to know, that there's no issue with the steel races and the ceramic balls!

If their was an issue we'd not be even having this conversation. Remember over TWENTY THOUSAND of the ceramic hybrid bearings have been installed worldwide. If any issues existed it would have gone viral in 2008, but it didn't, because, that didn't happen. The very first IMSR that was carried out used a ceramic ball bearing just like LN sells today. That engine is alive almost a decade after retrofit, and still has the original retrofit bearing.

The vast majority of ceramic bearings are hybrid, with silicon nitride balls, and specially treated steel races, just like this. This includes those used in aviation/ aerospace and every other application out there.

Those who want to omit all the wear parts step up the the IMS Solution.

The ims solution would be the best option for sure,but I'm thinking it will be about another year till ill be able to get hold of it where I live!
The question I asked before was,why do you "life" your bearings at such low milage/years since theyre so much better than the original bearings and many many cars are known to have gone beyond 100k miles on their original bearings? Will I still need to change my double row retrofit bearing in five or six years time,even if it has lets say 20k miles on it?

These are realistic periodic service recommendations. Unlike those who admit "they don't know" how long something will last that they may sell (but they sell it anyway as a lifetime part) the LN products have been truly developed. The lifespans that are stated came from the hourly ratings of the ball bearings, by the manufacturer, as well as what has been seen in practical applications.

No one (at LN) wants to set an expectation that ANY ball bearing will last forever, so from day one the components have had a service life, in years, and miles.

Yes, even if you put 500 miles on a bearing it can have too much time in service if it reaches the recommended service interval. Corrosive wear is real.
