Product Description
Ultra-Low Wear Si3N4 Balls Extend Bearing Lifespan 10X Over Steel
Silicon nitride (Si3N4) ceramic balls represent a significant advancement in bearing technology, offering exceptional durability and performance compared to traditional steel bearings. These components are revolutionizing industries that demand high-performance solutions.
Key Features of Si3N4 Ceramic Balls
  • High Heat Resistance: Withstands temperatures up to 1800°F (982°C) for high-temperature applications
  • Low Friction: Smooth surface ensures minimal friction, reducing wear and improving efficiency
  • Corrosion Resistance: Excellent resistance to most chemicals for use in corrosive environments
  • Lightweight: 60% lighter than steel, reducing centrifugal force and enabling higher operational speeds
Performance Advantages Over Steel
Enhanced Longevity: Ultra-low wear characteristics extend bearing life significantly, reducing maintenance and replacement costs.
Extreme Condition Performance: Maintains structural integrity in high-temperature environments where steel would degrade.
Improved Efficiency: Reduced weight lowers energy requirements and decreases machinery load.
Electrical Insulation: Non-conductive properties prevent electrolytic corrosion in electric motors and generators.

Frequently Asked Questions
What sizes and tolerances are available?
Diameter range: 0.5mm to 50mm (custom sizes possible). Sphericity as low as 0.1 µm (Grade 5 for ultra-precision bearings). Surface finish: Ra < 0.02µm (mirror polish for low friction).
Are silicon nitride balls FDA-approved for medical use?
Yes! Si3N4 is biocompatible (ISO 6474-1) and used in spinal implants, dental devices, and joint replacements due to its antibacterial properties.
