Really? It's pretty easy to find, if you know what it's for:

It's been several years since I had to try to find a listing based solely on the
design, though, and even then it's included in the core LDraw catalog if you dig
through the TECHNIC part chart.

Ah, no. The rubber ring is used to attach it to the micromotor, which only has
a little nub about the same size as a standard stud. The fact that it's a
rubber ring instead of any sort of axle/type attachment point helps prevent the
motor from burning out if the gearing binds up. Basically, it acts like a
slip-clutch. You'll find that the ring will also attach to a basic stud,
provided there isn't another stud immediately adjacent.
