It just holds the other things in place and spreads the strings. The actual bearing is separate pieces of "wood or metal" (I think I'd choose metal <G>). I would expect, though, that the screw holding it to the bridge might get loose over time (the wood would compress against it like a flange), so you might end up with a very serious lack of positive coupling of string to bridge (thinking of Ed's description of the whistling sound). But it seems like the real downfall of the idea was the fact that it was a cheap substitute, so was likely to be put together with less care, and on cheaper and less well-designed instruments.
