Category Details

A selection of Sapphire Synthetic Ceramic Balls. Extreme hardness, wear resistance, non-corrosiveness and chemical inertness.

  • Grades shown are AFBMA and ISO3290-1 which relates primarily to the ovality of the ball rather than the diametrical tolerance
  • General balls offered for sale may be from different ball lots, so the diametrical tolerance shown, indicates a variance that might be encountered if balls of different gauges are mixed, unless a ball gauge is specified for the part.
  • For diametrically critical applications, a special quote can be obtained for balls of a specified ball gauge.
  • Tolerances available on request. Grades shown are AFBMA / ISO3290-1.
  • Specific Gravity: 3.98. Grade 25.
  • Extreme hardness, wear resistance, non-corrosiveness and chemical inertness.
  • High mechanical strength.
  • Transparent (refractive index 1.76).
