This is mostly due to the additional time spent to perfect a quality ceramic ball.
Ceramic vs steel bearings.
They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here.
I know that there has been a debate between steel and ceramic bearings for a while but i have wondered how it effects the esk8 world as well.
This means lighter weight reels since the balls make up 50 75 of a bearings weight.
The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings.
Ceramic bearings vs steel.
Stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance.
Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.
Can be solid or a coating on stainless steel balls.
The different elements balls retainers and closures can change a bit.

Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.
Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings.
The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.
Initially the enduro bearing has lower friction at around 600km of use the ceramic bearing has worn a track into the comparatively soft steel races and the bearing friction starts to increase dramatically.
Cost of purchase for ceramic and steel bearings.
Optimization is possible for the disparity that exists between these parts.
Five different parts go into building skateboard bearings and longboard bearings.
The concept behind a bearing is simple.
Stainless steel bearings win the prize for load and speed ratings.
If solid ceramic they re lighter than stainless steel by as much as 60.
The wear rate of ceramic ball bearings is significantly less than stainless steel especially when lubricated.
