Well, this is very impressive for sliding surfaces under worst
possible conditions - stainless against stainless under tons/sq. In.
pressure. Galling is expected under these conditions, and the
Krytox really proves it can prevent that, even at high temperatures.
But, what about rolling bearings? What you want there is something
that prevents rubbing away of the hardened surfaces, but not
necessarily something that cuts sliding friction nearly to zero.
That could prevent the balls from rolling at all, which would be
bad for a spindle ball bearing.
