High-performance silicon nitride ceramic products are manufactured using an advanced cold isostatic pressing-hot isostatic pressing (HIP) sintering process, achieving material properties that reach the internationally advanced level of similar products. Components combining metal and ceramic are produced according to special usage requirements.

Silicon nitride ceramic bearings have the following advantages:

1. Low density, lightweight, 59% lighter than steel balls, reducing centrifugal force during bearing operation and thus reducing friction.
2. Low coefficient of thermal expansion, 1/4 that of steel, able to withstand temperature fluctuations.
3. Elastic modulus 40% higher than steel, less elastic deformation under stress, reducing machine vibration.
4. Low coefficient of friction, high temperature resistance, long service life.
5. Non-magnetic, electrically insulating, no adhesive wear.
Mainly used in: high-speed/ultra-high-speed bearings, high-precision bearings, high/low-temperature resistant bearings; it can also be used as valve balls and measuring balls in chemical pumps, high-temperature pumps, and metering pumps.
