Self-Lubricating Si3N4 Ceramic Balls for Bearings

Properties of Si3N4 Ceramic Balls

1. Elevated Limit Speed:
   The low density of silicon nitride ceramic (just 40% of steel) significantly reduces centrifugal force, enabling higher limit speeds for our Si3N4 ceramic ball bearings.

2. Extended Service Life:
   With its lightweight design, reduced centrifugal force, and lower raceway load, the silicon nitride ceramic ball exhibits minimal wear and offers a lifespan exceeding 5 times that of steel ball bearings.

3. Broad Temperature Range:
   Resistant to high temperatures and possessing a low coefficient of thermal expansion, Si3N4 ceramic bearings maintain consistent clearance across a wider temperature range compared to steel bearings.

4. Lubrication-Free Operation:
   Thanks to its self-lubricating properties, our silicon nitride ceramic ball bearing requires no additional lubricating oil or grease, making it ideal for high-vacuum and high-cleanliness applications.

5. Excellent Corrosion Resistance:
   Silicon nitride ceramic balls are highly resistant to acid, alkali, and other chemicals, ensuring their suitability for use in corrosive environments.

Applications of Si3N4 Ceramic Balls

1. Chemical Industry:
   Leveraging their corrosion resistance, Si3N4 ceramic bearing balls are widely used in liquid and gas conveying equipment, particularly in corrosive environments such as pickling machines and chemical pumps.

2. Electronics Industry:
   Known for their low friction coefficient and lightweight design, Si3N4 ceramic balls are ideal for precision machining equipment and electronic components, including chip manufacturing devices, hard disk motors, and high-precision machine tools.

3. Machinery Industry:
   Boasting high compressive strength, good toughness, wear resistance, and low friction, Si3N4 ceramic bearings are widely applied in high-speed motors, hydraulic pumps, precision machine tools, wind turbines, and high-speed trains, ensuring long service life and operational stability while reducing equipment maintenance costs.

4. Aerospace Industry:
   With their non-magnetic properties, electrical insulation, high temperature tolerance, high rigidity, and wear resistance, Si3N4 ceramic bearing balls play a crucial role in aerospace applications, such as aircraft engines, gyroscopes, and inertial measurement devices.

5. Metallurgy & High-Temperature Environments:
   Si3N4 ceramic bearings, resistant to high temperatures and thermal shock, are extensively used in metallurgical processes, rubber and plastic production equipment, and other high-temperature environments.
