💡 Why use Si3N4 ceramic ball bearings in miniature applications?
Si3N4 balls are lighter, faster, and tougher than steel.

• Resist wear and heat under high-speed loads

• Reduce vibration for smoother performance

• Corrosion-resistant and non-conductive

• Perfect for lab gear, electric motors, and robotics
