Five different parts go into building skateboard bearings and longboard bearings.
Ceramic bearings vs steel bearings longboard.
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.
The different elements balls retainers and closures can change a bit.
Things don t slide or roll.
Rolling resistance is the key trump card promoted by ceramic bearing fans.
The concept behind a bearing is simple.
Ceramic bearings vs steel.
Optimization is possible for the disparity that exists between these parts.
Because ceramic bearings are rounder with a smoother surface and more uniform size friction is reduced and that can contribute to a less energy required.
The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.
Ceramics are known for heat reduction making them able to spin fast at higher speeds but generally the ceramic ball bearings are encased in a steel outer inner race.
