Ceramic bearings vs steel spinners.
Trying to figure out the difference between fidget spinner bearings.
Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.
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.
May 01 2017 you really can t talk about spinners for long without coming on to the subject of bearings.
The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.
