Description

Ball bearings Ceramic Si3N4 - 608 - Black ball

Dimension: 8x22x7 mm (608)

Silicon Nitride (Si3N4): A new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimum lubrication makes this material perfect for harsh conditions. Si3N4 is anti-magnetic. Maximum useful temperature is 2552°F (1400°C).

Technical

Si₃N₄ SILICON NITRIDE - The most widely used type of ceramic due to very high resistance to wear and abrasion in general. It has a low coefficient of ther­mal expansion (25% of that of steel balls) and a weight 60% lower than steel. It has a micro-structure specially designed for applica­tions subject to great stress. It does not require lubrication, it is resistant to corrosion, anti-magnetic and electrically insulating, and it continues to be efficient at high temperatures up to +1400 °C. It combines extreme hardness with a high precision ball. Si₃N₄ balls are widely used in high precision bearings in the airspace industry, for machine tools, measurement instruments, mecha­nical centrifuges, radar and missiles, pumps and compressors.
