Silicon Nitride Ball (Si3N4)

• Size Range: φ0.4mm–φ100mm

• Precision Grade: G5-G40

• Hardness: HRC75-80, HV: 1300-1600

• Density: 3.2g/cm³

Product Features:

1. Lightweight Design: With a density that is only 1.59% of steel balls, it generates lower centrifugal force and deformation at high speeds, enhancing operational efficiency and stability.

2. Exceptional Elasticity: The elastic modulus is 44% higher than that of steel balls, allowing it to bear higher loads while maintaining deformation stability.

3. Outstanding Wear Resistance: Extremely high hardness ensures excellent durability and extended service life.

4. High-Temperature Resistance: Performs stably at temperatures up to 1050°C, making it suitable for extreme environments.

5. Smooth Surface Characteristics: Surface roughness can reach Ra 0.01-0.1μm, effectively reducing friction coefficients.

Applications:

Silicon nitride balls are ideal for demanding applications such as high-speed/high-temperature bearings, vacuum equipment, cryogenic machinery, oil drilling tools, aerospace, chemical machinery, and the electronics industry. They are especially suited for environments requiring corrosion resistance, high-temperature tolerance, and superior wear resistance, making them the perfect choice for high-performance equipment.
