Ball definitions:

Ball gage:prescribed small amount by which the lot mean diameter should differ from nominal diameter, this amount being one of an established series of amounts
Ball gage deviation: difference between the lot mean diameter and the sum of the nominal diameter and the ball gage
Ball diameter variation: difference between the largest and the smallest actual single diameter of the ball
Case depth:distance measured radically from the surface of the ball to a point where the hardness becomes the equivalent of RC 50 this term is applicable to case hardened balls only
Deviation from/spherical form: greatest radial distance in a radial plane between a sphere circumscribed around the surface of the ball and other points on the surface of the ball
Grade: specific combination of dimensional form and surface roughness tolerance ball grade is designated by a grade number ex G100, 200
Hardness: measure of resistance to penetration of the ball surface or truncated flat of the ball by a specific indenting shape
Lot mean diameter: arithmetic mean of the mean diameter of the largest ball and that of the smallest ball in the lot
Lot: definite quantity of balls manufactured under conditions which are presumed uniform and which is considered and identified as an entity
Lot diameter variation: difference between the mean diameter of the largest ball and that of the smallest ball in the lot
Mean diameter of a ball: arithmetic mean of the largest and the smallest actual
single diameters of the ball
Nominal ball diameter: diameter value that is used for the purpose of general identification of a ball size, e.g. 1/4", 6mm
