Si3N4 Silicon Nitride Balls

（Si3N4 Silicon Nitride） CERAMIC BALLS

Silicon nitride (Si3N4) ceramic balls are commonly used in bearings and offer high heat resistance and low friction. Silicon nitride balls are commonly used in industries such as military, aerospace and defense, hybrid bearings and all-ceramic bearings.

• Specifications φ0.4mm-φ100mm
• Grade G5-G40
• Hardness HRC75-80、HV:1300-1600
• Density 3.2g/cm3
• Performance 

       1.59% lighter than steel balls, which means less centrifugal force and wears less grooves at high speeds and                        accelerations

       2. The elastic modulus is 44% larger, which means less deformation under load.

       3. Smaller friction coefficient.

       4. The linear expansion coefficient of silicon nitride ceramic ball is 3.2×10-6/K, which is almost 1/4 of bearing steel,                and can endure high temperature.

       5.Excellent surface finish can be achieved, Ra can be 4~6.
       6. Can endure high temperature, high hardness and strength up to 1050 ℃.

APPLICATION OF CERAMIC BALLS

• Zirconia Ball，Zro2 Zirconia ceramic balls are mainly used as valve balls, full ceramic balls, measuring balls, track balls, and fine grinding balls. They can be used in high temperature, corrosion resistance, insulation, magnetic insulation, non-lubrication and other occasions. They are ideal for replacing steel balls in corrosive occasions. Material.
  As a valve application, zirconia ceramic balls have been successfully used in high-pressure homogenizers, diaphragm pumps, metering pumps, oilfield oil pumps and other equipment.
  
  
• Silicon Nitride Ball Various bearings (high-speed/ultra-high-speed bearings, high-precision bearings, vacuum bearings, high/low temperature bearings, non-magnetic bearings, high-precision ball screws, etc.), can also be used as valves in chemical pumps, high-temperature pumps, and metering pumps ball, measuring ball
  Silicon nitride ceramic balls are generally assembled into hybrid bearings, which can be used in chemical industry, metallurgy, food, oil field, electronics, etc.
  
• Silicon Carbide Ball，SiC Typically used in bearings, valves, aerospace, machinery
