Trying to figure out the difference between fidget spinner bearings.
Ceramic bearings vs steel bearings spinner.
The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings.
Full ceramic and hybrid ceramic.
Hybrid ceramic have ceramic ball bearings while their races cage and shields are stainless steel.
The ceramic balls are often silicon nitride or equivalent.
Watch this video and you will be set.
They use ceramic balls and usually a steel inner and outer race.
A top class set of steel bearings as compared to a much promoted ceramic bearing is just as high performing.
Ceramic bearings vs steel bearings ceramic materials offer superior corrosion and heat resistance higher dimensional stability and lower density which facilitates high speed.
The ceramic balls are lighter and roll better at least 3 times compared to steel balls.
They will both also cope with higher temperatures than chrome steel but ceramic bearings also win here.
Ceramic is far more superior compared to steel bearings.
Ceramic bearings exist to help manage heat in high rpm applications.
Steel bearings are commodity items that are composed of hardened steel balls and a steel inner and outer race.
Stainless steel bearings win the prize for load and speed ratings.
At the lower end of the market you are likely to see spinners employing full stainless steel bearings.
Ceramic is brittle and unlike steel does not handle vertical loading well.
Cost of purchase for ceramic and steel bearings.
They reduce the rolling resistance on the wheels hence increase the precision for the balls inside and make the wheel roll faster.
This makes their application in ball bearings somewhat impractical for both longboard and skateboard.
This means that both the bearing s races cage if there is one and balls are all stainless steel.
Bearings can be made with chrome steel stainless steel or carbon alloy steel.
I showed and tested full ceramic bearings stainle.
Full ceramic have ceramic ball bearings as well as the races cage and shield made from ceramic material.
Performance is the litmus test of a bearing.
While a formula 1 engine revving to 15 000 rpm can create a lot of heat that can deform and swell steel bearings.
It takes weeks for a kogel ball to sit in a tumbler and be.
Ceramic bearings are in actual fact hybrid.
Stainless steel bearings and full ceramic bearings are both corrosion resistant but the ceramic bearings have greater corrosion resistance.
