I was thinking I'd seen them on suspension coils on a high end auto, BMW or MB maybe? Basically as the coil compresses it tries to rotate, but there's more resistance in compression or loading than unloading. By adding the bearing you get a smoother cycle.
I'ze just wondering if anyone had ever built some heads like that!

How are these springs rotating without a bearing and without wearing the head down?
