Silicon Nitride Balls for Bearings
Localization of Silicon Nitride (Si₃N₄) Bearing Balls, a Core Material in High-Value-Added Industries like Electric Vehicles (EVs) and Semiconductors
Silicon Nitride (Si₃N₄) Balls
Our Silicon Nitride (Si₃N₄) ceramic balls are produced using Modified SRBSN technology, achieving high strength, superior fracture toughness, and excellent wear resistance. This makes them ideal as essential components in high-speed, high-performance bearings due to their strong resistance to rolling contact fatigue.
