LN engr. ims ceramic bearing

[thom4782]

I'm really confused now. One picture in this thread shows that the LN bearing is unsealed; another picture shows it as sealed. I also looked at pictures on the Pelican Parts site. The single row looks sealed on the stud side of the bearing. The dual row LN bearing looks unsealed to me.

I guess you have to have bought one to understand. I get it now.

Mine is the LN Eng. ceramic bearing - it IS indeed OPEN on one side. Thanks @ Meir - it looks identical to yours.

The bearing also came with the "LN Engineering.com IMS Retrofit" sticker w/ unique serial#. Thanks @Jager. NOTE: My number is in the 6600's - meaning LN have sold a few thousand of these since yours!

I will be glad to put the whole thing in the rearview! I am getting grumpy not having my racecar.

I've had a "Porsche-jones" for a couple weeks now! Can't get my fix. Tried my wife's Honda and left it 'ticking' in the drive but didn't feel much better. Nothing really takes the place. One drop of oil and your life can change! Carpe Porsche!

Could be that LN decided to remove the seal down the road.
This way or the other, oil still gets in there, just likes it gets into the OEM bearing.

Sorry for all the confusion. The bearing that I have is what Jager has shown. The confusion was created for me after seeing the ceramic bearing showing a metal cage.

I emailed Michael a picture of it at LN engineeriring and he verified that my bearing is indeed the none sealed ceramic bearing.

Thx for all your input.

Meir, the LN ceramic bearing has never had the inner seal. It invites the oil mist within the crankcase in as opposed to the Porsche and Pelican steel bearing which use an inner seal and lube with grease with some oil sometimes getting by the seal and washing out the grease thus allowing a less lubed steel bearing.

A comparison of the two kits is here.

That's what I thought mike.
But Jäger is definitely showing an LN bearing, and it looks like it has an outer seal.
Unless the picture is showing the "back" of the bearing.

I purchased LNE bearings mid 2011. All of them have the seal. In this photo the bearing on the left is the factory original. The center bearing and the bearing on the right are LNE bearings.

My LNE IMSB retrofit bearing looked very similar to the factory bearing, ala Jäger's photos. I bought mine directly from Charles at LNE via phone. There was no exposed bearing race on the bearing I bought.
