what kind of grease do I use for my SOTA Sapphire bearing?

It is a very heavy, tacky oil they are using. Sota will be happy to sell you a small plastic dropper bottle which will last you 4 lifetimes. Go to their website and get the phone number. If a woman answers with a husky voice that’s Donna.

thanx

I thought the bearing is sealed?

In any case if you're DIY then I'd be interested in the results.

Maybe, but if the gentleman has the original inverted bearing with the sapphire cup, then if I recall correctly that bearing used white lithium grease.

@fosolitude check with SOTA before you wreck your bearing.

They've always been in Elkhorn as far as I know.
