Silicon nitride balls have the following advanced characteristics:

Fine crystals never rust and can roll without oil or oil.

Our silicon nitride ball manufacturing capabilities range from 0.5mm to 38mm.

Purpose:

The most common use of silicon nitride balls is bearings. The thermal expansion coefficient of silicon nitride bearing steel ball is only 25% if most steel balls are used, so the friction generated by the bearing is smaller with the increase of heat. The low thermal conductivity of the silicon nitride ball reduces the heat absorbed, thereby reducing the requirements of the cooling system.
