LN Eng IMS Bearing Question

On the factory IMS it has an "O" ring on the center stem which the flange goes over
to keep the oil in.
This makes sense to me.

But I don't see how the LN bearing achieves this.

I look at pictures on line and it does not show how it does this.

Does it have a groove cut on the inside on the flange (for an "O" ring) where it slides
over the center stem? (in reverse of the OEM system)

I just like to know how things work before I drop a bunch of cash.

Thanks

The LN bearing uses an o=ring on the center bolt, but no undercut as that was a weakness in the factory bolt that led to many failures:



And the design does work, we have not had one leak yet.
