Yes, I've seen it in cassette decks, and also in a couple of 35mm slide 
projectors (where there's a rubber drive wheel on the motor which engages 
with the rest of the mechanism, or at least it would, if it hadn't turned 
to goo)

I also had a pair of identical QIC drives where one roller was bad and the 
other just fine.
