silicon nitride Ceramic Bearing

Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetism, insulation, self-lubrication, high speed, etc. In high speed, high temperature, low temperature, big temperature change, vacuum, insulation requirements, non-conductive magnetic and other harsh working environment, high-performance ceramic bearings are the ideal bearing to replace the current use of steel bearings. The service life of ceramic bearings is more than 3 times higher than that of steel bearings, which can significantly reduce downtime and improve the operating efficiency of machinery.


Main Properties

✓ high temperature resistance ✓ cold resistance
✓ wear resistance✓ orrosion resistance
✓ anti-magnetism✓ insulation
✓ self-lubrication✓ high speed


Main Type

1. ZZ type:Bearing is sealed by PTFE or PEEK retainer

2. Bearing comes without seal on any side

3. Bearings are made of Si3N4 or ZrO2 ceramic

4. Material of Balls Type:Si3N4 or ZrO2 Ceramic Balls

5. Bearing Cage:Si3N4 / ZrO2 / PTFE / Nylon

6. Bearing Model:6000/6300/1600/R series


Advantages of Silicon Nitride Bearing 

1. It can be utilized in environments with strong acid, strong alkali, and seawater, exhibiting excellent corrosion resistance.

2. High temperature resistance, the strength and hardness of the silicon nitride ceramic ball are almost unchanged at 800C.

3.It is non-magnetic, insulating, and can be used in a magnetic field without conducting electricity.

4. Light weight, 1/4 lighter than ordinary bearings, and its density is 3.20g/cm3.

5. High rigidity, high strength, its hardness is twice higher than that of bearing steel, and its elastic modulus is about 1/3 higher.

6. High-speed rotation, the weight of the rotating body (ball) is light, and the centrifugation is small when rotating.

7.Its linear expansion coefficient is 3.2×10-6/K, approximately 1/4 that of bearing steel.

8. The self-lubricity of silicon nitride ceramic bearing balls can solve the pollution and inconvenience of adding lubricating medium.

9. Chemical resistance, mechanical strength, destructive toughness, and low thermal conductivity.
