Useful Terms and Definitions used to describe Precision Balls.

Nominal Ball Diameter - The diameter value that is used for the general identification of a ball size.

Single Ball Diameter - The distance between two parallel planes tangential to the actual ball surface.

Diameter Tolerance per Batch - The allowed difference between the smallest measured ball diameter and the largest ball diameter within the same batch or lot.

Batch or Lot - A definite quantity of balls manufactured under conditions presumed to be uniform and which is considered an entity.

Sphericity - A measure of roundness expressed as the difference between the measured roundness of a ball and a perfectly round ball.

Surface Finish or Roughness - A measure of the texture of a surface. It is quantified by the vertical deviations of the actual surface from it's ideal form, if these deviations are large the surface is rough; if they are small the surface is smooth.

Hardness - A measure of resistance to penetration as determined by specific methods, usually Rockwell or Vickers Hardness.
