💡Why are Si3N4 ceramic hybrid bearings used in high-speed fidget spinners?
Silicon nitride balls are a solid choice when you want ultra-smooth motion and top-notch durability:

• Lighter and harder than steel, so they spin longer

• Low friction means faster starts and longer glide

• Non-corrosive and non-magnetic - ideal for any environment

• Nylon cage keeps noise down and speed up
