Roller Skates Ceramic Ball Inline Skate Bearings


1.Could be used at higher temperature. Ceramic maintains mechanical properties at high temperature,ceramic bearing can be used at elevated temperature.
2.Corrosion resistant. ceramic bearing are more suitable for chemical industry application.
3.More suitable for temperature-variation application. Because thermal expansion co-efficiency of ceramic are smaller than metal, so the change of clearance of ceramic bearing is smaller than that of metal bearing.
4.More resistance to seizing due to smaller thermal expansion when skateboarding a long time.
5. Ceramic skateboard bearing can work under poor lubrication, because ceramics are self-lubrication. ceramic bearing could be used at high-vacuum environment.
6.Could be used as insulation bearing and can prevent Electrical Arcing because ceramics is not electrical conductor.
7.Could be used in magnetic environment because ceramics do not respond to magnetic forces.
