It's another lubricant, no more, no less. Maybe it is superior to other common choices for turntable bearings. Maybe not. I think Miguel raised an interesting question, but none of us is qualified to say yea or nay, since none of us has used it for this application. But it's not "magic". The first thing that I would verify before using it on a turntable is whether it is corrosive for either the bearing (which is typically a ball made of an exotic metal) or the thrust plate. If not, have fun.
