5 FAQs of 4mm Silicon Nitride Si3n4 Ceramic Porcelain Ball for Bearing

FAQ: 4mm Silicon Nitride (Si3N4) Ceramic Balls for Bearings

Why pick silicon nitride balls over steel ones?
Silicon nitride balls are much harder than steel. They last longer. They resist wear far better. This reduces friction. Lower friction means less heat. Less heat helps your bearing run smoother. It also extends the bearing’s life significantly.

How hot can these ceramic balls handle?
These Si3N4 balls handle very high temperatures. They work fine well above 800°C. Steel balls weaken much earlier. Heat makes steel balls expand. Ceramic balls expand less. This keeps your bearing stable. Performance stays consistent even in hot environments.

Do they resist chemicals?
Yes, silicon nitride has excellent chemical resistance. It won’t rust like steel. It handles many acids and bases well. It performs reliably in harsh environments. Corrosion won’t damage these balls. This makes them good for tough applications.

Do they conduct electricity?
No, silicon nitride is an electrical insulator. It won’t conduct electricity. This prevents electrical arcing inside the bearing. It stops electrical currents from damaging the balls or races. This is vital for electric motors and generators. It avoids electrical erosion problems.

Are they lighter than steel?
Yes, silicon nitride is much lighter than steel. These ceramic balls weigh about 60% less. Reduced weight lowers centrifugal force at high speeds. This reduces stress on the bearing. It also cuts energy loss. Less weight means less power needed to spin the bearing. This improves efficiency.
