So that would be bearings made in China and seals made in India?? Sorry, I couldn’t resist! [emoticon]

We =really= wanted oil-bath axles on the PJ GN we bought last year, but we just don't run it enough to keep the seals in condition. On advice of our "trailer guy", we went with triple singles with 7k EZLubes instead of tandem duals with oil-bath. Yeah, gave up about 3k in GVW, but that would have been waaaay overkill for our needs anyway.

Since you asked,

OH, I should have taken a pic of the clear cap seal. That is where many oil bath systems leak because of PIZZ poor "O" rings. I used "AS568-230 BV75 Fluorocarbon FKM O-Rings 75 Durometer Brown" from the O-RING STORE LLC for $1.13 each. They don't tear!

I recently learned what a true oil bath seal is. The inner part of the seal grabs the spindle and does NOT spin on it. So basically there is the outer and inner part of the seal that rides within its self. Hope that makes sense.

DRV for a while was using Oil Bath System but gave up because of all the complaints with oil residue or leaks. Problem??? You guessed it PIZZ poor quality parts.

I think I follow you; so is it some sort of mechanical seal?

It looks very similar to a regular seal. Best to look up the seal number on National’s site to see what they show.

Maybe someone with better computer skills could post something.

Replace the wheel bearing. Why not, they're super cheap! Replace all of them at the same time. Just my recommendation. Again, the bearings themselves are an inexpensive cost to your expensive 5er

Probably Inpro bearing isolators.

The top "D" surface seats into hub like normal. The lower "D" grips the spindle, so there is no spindle wear.

You could use this on a grease system also. The National Seals are US Made.
