2016.11.02 Dymco’s low-inertia roll


Hello, I am Mukaisaka at Dymco R&D division.

Today’s topic is the low-inertia roll which Dymco started to offer recently.

The mechanism of this product is a thin metal sleeve (electrically casted nickel) which revolves around inner cylinder floating on thin air layer as illustrated here.
 


As you can imagine easily, the mechanical loss of rotation is minimal.

Even a light weight of small coin (one gram) is enough to initiate the rotation.

See the demonstration video.
