I have been told that there is a sealed axle bearing with a o-ring machined into it to replace the old stlye axle bearing and race combo. I have been looking trying to find it no luck, I was told National Bearing makes it. If not mistaken nthe bearing measurements are 1.56" inside dia. and 2.87" outside, in that general area, I dont have my notes handy, any help with a part # and brand would be great. Thank you

that is all that is stenciled on my bearings hope it helps

 

call jawsgear dude!

 

My O Ring style bearings leaked, I picked up some replacements from napa when i changed to 3in studs and the new bearings are smooth and havnt leaked yet, 500mi only though

 

The bearings that came from Moser with the o ring were replaced with the non o ring styles. If you contact Moser they can tell you the p/n. I have no issues with them, and the new ones can be picked up anywhere.
