Industrial Metal Ball Grades

US Ball subscribes to the A.F.B.M.A. Industrial Ball Grades standards which are listed in this chart. Definitions of the listed custom metal ball tolerances are likewise listed below. The most common ball tolerances are listed. All the metal balls grades include many other tolerances which have not been listed. From metric to miniature to large and small metal precision balls.

Allowable deviation from spherical ball form: The greatest radial distance in any radial plane between a sphere circumscribed around the precision ball surface and any point on the industrial ball surface.
