Ceramic Bearing Spin Test 12 minutes

This is a 20" tire for a supermileage car. The hub was custom made out of a solid piece of aluminum. The bearings are full ceramic with no seals. The one bearing is not quite lined up as well the other, but it spins very well. The tire was spun by hand at ~300 rpm before the camera was turned on.

Later tests with the front wheels provided a spin time of 16:55. It was observed that most of the resistance at over 100 rpm was coming from from the air drag. It only take about 5 minutes to go from 300 to 100 rpm, but it takes 10 minutes to go from 100 to 0 rpm.

To make this even more impressive, the tire only weighs 150 grams, which is super light.

The new wheels will have bladed spokes and lighter rims.

Great bearing! Do not forget that bearing resistance is still linear proportional to speed ;) it is not only air drag
