Please stop saying that we cannot lube behind the seals nor under the rollers. That's just wrong.
Rusting (swelling) pins are the reason why kinks appear. If water can get past the rings, so does lube. It may be because the seals are damaged sooner or later, but that doesn't matter.
You want lube to be the first to have the opportunity to get past the rings. Neglect will kill your chain, and dry seals will fail faster too.
As for rollers, they are obviously not sealed, you can see it with your own eyes. These are the ones taking the pressure, while the pins take the tension.
