Category Details

A selection of Zirconia Ceramic Balls. Outstanding wear resistance. Excellent thermal and chemical resistance.

  • 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.
  • Grades shown are AFBMA and ISO3290-1.
