The specific gravity of silicon nitride is relatively low among the specific gravities of ceramic balls, at 3.2 g/cm³. Its hardness can reach HRC 75-80 and HV 1300-1600, with an accuracy of G5. It can maintain stable performance even in high-temperature environments of 800°C or even 1200°C. The self-lubricating property of silicon nitride is quite good, it can withstand most acids and bases, and it is also a very good electrical insulator.

Product Name	Si3n4 Ceramic Ball
Density	3.2g/cm3
Grade	G5-G40
Hardness	HRC75-80,HV1200-1300
Applications	High-speed / ultra-high-speed bearings, high-precision bearings, vacuum bearings, high/low-temperature bearings, non-magnetic bearings, high-precision ball screws, can also be used in chemical pumps, high-temperature pumps, metering pumps to serve as valve balls, measuring balls. Silicon nitride is usually assembled into mixed bearings, which can be applied in chemical, metallurgical, food, oilfield, electronic lighting and other industries.
Feature	1. 59%, lighter than the steel ball, which means less centrifugal force and fewer slots being worn at high speed and acceleration. 2. The elastic modulus is 44% higher, which means less load deformation. Performance 3. A smaller friction coefficient. 4. Only 1/4 the thermal expansion coefficient of steel, capable of withstanding high temperatures. 5. Can achieve excellent surface finish, Ra can be 4-6. 6. Can withstand high temperatures, high hardness and a strength up to 1050°C.
