Product Description


zirconia ball Zro2

① Zirconia Ball,Zro2
  • Specifications φ0.1mm-φ63.5mm
  • Grade G5-G40
  • Hardness HRC70-HRC73、HV:1100-1300
  • Density 6g/cm3
  • Performance

1. High strength and high toughness, no broken beads under high-speed impact.

2. Good sphericity and smooth surface.

3. Ultra-low wear, wear resistance is 30-50 times that of glass beads, 5 times that of zirconium silicate beads, and 6-8 times that of alumina beads.

4. High density and high grinding efficiency.

silicon nitride ball Si3N4

② Silicon Nitride Ball,Si3N4
  • 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 ℃.

silicon carbide ball SiC

③ Silicon Carbide Ball,SiC
  • Specifications φ0.5mm-φ50mm
  • Grade G10
  • Hardness HRC85-90 HV: above 2100
  • Density 3.1g/cm3
  • Performance

Silicon carbide ceramic balls have stable performance, and silicon nitride has good overall performance. Compared with steel, its mass is lighter than steel, its friction coefficient is smaller, its motion performance is better, its elastic modulus is 50% larger than that of steel, its thermal expansion coefficient is smaller than 25% of that of steel, it can maintain high strength and hardness before 1000℃ under high temperature, and it is resistant to corrosion. No rust, non-magnetic, can work without oil lubrication.

  • 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.
