The 8Mode Ceramic Hybrid is an outstanding 608 type bearing that is ideal for fidget spinners.
Ceramic Hybrids combine ceramic ball bearings with stainless steel raceways.
The hard ceramic provides lower friction and a smoother feel with longer spin times.
Ceramic Hybrids can last 5-20 times longer than steel.
They are more corrosion resistant than steel bearings.
Better performance than stainless, but not quite as good as a full ceramic bearing.
