The different elements balls retainers and closures can change a bit.
Ceramic vs steel bearings.
Can be solid or a coating on stainless steel balls.

Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.
Things don t slide or roll.
The wear rate of ceramic ball bearings is significantly less than stainless steel especially when lubricated.
The concept behind a bearing is simple.
A ceramic bearing is also harder than steel bearings up to 30 which improves durability and they also don t rust so less maintenance should be required.
If solid ceramic they re lighter than stainless steel by as much as 60.
Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.
This is mostly due to the additional time spent to perfect a quality ceramic ball.
Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.
Stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance.
This means lighter weight reels since the balls make up 50 75 of a bearings weight.
Stainless steel bearings win the prize for load and speed ratings.
The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.
Ceramic bearings vs steel.
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.
They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here.
Five different parts go into building skateboard bearings and longboard bearings.
Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings.
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.
