Silicon Nitride (Si₃N₄) bearings are high-performance ceramic bearings known for their exceptional hardness, lightweight nature, and outstanding resistance to wear, heat, and corrosion. Compared to traditional steel bearings, silicon nitride bearings offer superior durability and efficiency, making them ideal for extreme environments and high-speed applications.

Key Features:

• High Hardness & Wear Resistance – With a hardness second only to diamond, these bearings exhibit excellent wear resistance, ensuring long service life.
• Lightweight & High-Speed Performance – Silicon nitride is about 60% lighter than steel, reducing centrifugal forces and enabling higher rotational speeds.
• Superior Thermal Resistance – Can withstand temperatures up to 1400°C without degradation, making it suitable for high-temperature environments.
• Low Friction & Self-Lubricating – Reduces friction and operates efficiently with minimal lubrication, improving energy efficiency.
• Corrosion & Chemical Resistance – Highly resistant to acids, alkalis, and oxidation, making it ideal for harsh industrial environments.
• Excellent Electrical Insulation – Unlike steel bearings, silicon nitride bearings do not conduct electricity, making them perfect for high-voltage applications.
• Exceptional Thermal Shock Resistance – Can endure rapid temperature fluctuations without cracking or failing.
