Remember the drill alone without spinning the tire took 1 38 amps.
Ceramic bearings vs steel motorcycle.
A top class set of steel bearings as compared to a much promoted ceramic bearing is just as high performing.
This discourse holds true not only for the bearings of skateboards and longboards but also for motorcycle and bicycle bearings.
The hybrid ceramic bearings had a long free spin time.
Cost of purchase for ceramic and steel bearings.
The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings.
That is 2 75 times longer than the steel ball bearings.
Worldwide ceramic bearings have 40 less friction than steel and up to 60 less rotating weight.
It takes weeks for a kogel ball to sit in a tumbler and be.
Ceramic bearings in my opinion are just not worth it.
Next was the amperage that the drill needed to spin the wheel.
This is mostly due to the additional time spent to perfect a quality ceramic ball.
The drill only needed 1 42 amps to spin the hybrid ceramic bearing wheel.
Sorry for strangling the hype.
The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.
Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings.
