They only move a little bit, enough to damp teh most common vibrations of lesser magnitude, the ones you would never feel or know about otherwise. The grooves the inner part rotate in are wideth enough to provide some stability. So you get the best of both worlds, attentuation and stability all in a nice simple package. I never realized how great those things really are. Almost got rid of them a number of years back being only from Radio Shack and all.
