Grades shown are AFBMA and ISO3290-1 which relates primarily to the ovality of the ball
General balls offered for sale may be from different ball lots, so the diametrical tolerance indicates a variance that may be encountered if balls from different lots 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
Outstanding wear resistance. Good thermal and chemical resistance.
High hardness. Grades shown are AFBMA / ISO3290-1.
High strength over a wide temperature range.
High fracture toughness.
Outstanding wear resistance.
