Yes, generally rubber bushings are supposed to twist, with inner and 
outer being stationary on their mounting surfaces.

Presumably something that rotates a lot needs a thicker rubber section 
than one that rotates just a little. It seems to me that some of the 
Corvair sway bars have bushings with pretty thin layers of rubber - do 
they not rotate much, or are those bushings expected to slip?
