Silicon Nitride Balls

Uses:
The most common use for silicon nitride balls is in bearings.  Silicon nitride bearing balls have a coefficient of thermal expansion just 25% of most steel balls, so there is less friction generated in the bearing as heat increases.  The low thermal conductivity of silicon nitride balls reduces the amount of heat absorbed, thus reducing cooling system requirements.  Parts can be manufactured to your specifications.  online contact form

What are Silicon Nitride Balls?

Silicon nitride is a hard ceramic having high strength over a broad temperature range, moderate thermal conductivity, low coefficient of thermal expansion, moderately high elastic modulus, and unusually high fracture toughness for a ceramic. This combination of properties leads to excellent thermal shock resistance, ability to withstand high structural loads to high temperature, and superior wear resistance. Silicon nitride is mostly used in high-endurance and high-temperature applications, such as gas turbines, car engine parts, bearings and metal working and cutting tools.
