R188 ybrid ceramic bearing /Ceramic ball yoyo bearings/Hand Spinner Fidget bearing
Today, ceramic bearings are the hottest thing in yoyo technology. They are lighter, smoother, stiffer, harder, and corrosion resistant.
These characteristics allow for a wide range of performance enhancements in bearings.
Ceramic dissipates heat quickly, reducing friction and wear while maintaining a precision smooth surface.
Today's leading edge ceramics are made with Silicon Nitride (Si3N4) and have characteristics similar to the heat absorbing, highly resilient tiles on the Space Shuttle.
Yoyo Ceramic Bearings are specially designed for competitive Yoyo enthusiasts.
