Five different parts go into building skateboard bearings and longboard bearings.
Ceramic bearings vs steel bearings longboard.
Rolling resistance is the key trump card promoted by ceramic bearing fans.
Optimization is possible for the disparity that exists between these parts.
The concept behind a bearing is simple.
Things don t slide or roll.
While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4.
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.
Ceramic bearings vs steel.
The graph below shows a comparison between two steel bearings skf and ntn and a ceramic bearing enduro.
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.
