Ceramicspeed (Ceramic) bearings versus Steel Bearings... An engineering explanation

Ceramic bearings versus steel bearings, the debate has gone on for a long time. I decided to test the capabilities of Ceramicspeed, Enduro, A cheap ebay bearing and the big bearing manufacturers. The big bearing manufacturers win hands down. The vast majority of friction comes from the type of bearing seal. Contact bearings have significantly more friction than non contact types. The choice of balls has little effect. Conclusion: Ceramicspeed are overpriced and inferior. Checkout my website http://www.hambini.com Don't forget to subscribe to this channel!    / hambini
