One or two slanting arrows controlling wobble about an axis.
Also known as: Circular runout, Total runout
Runout limits how much a surface wobbles as the part turns about a datum axis. Circular runout, one arrow, checks each cross-section separately; total runout, two arrows, checks the whole surface at once and is the stricter of the two.
Limit the variation of a surface measured as the part rotates about a datum axis.

Come in two grades: circular runout, drawn with one arrow, checks one cross-section at a time, while total runout, drawn with two, controls the entire surface.

Are among the few characteristics that can be verified with an indicator and a rotating fixture rather than a coordinate machine, which is part of their appeal.

One or two arrows leaning at the same angle, drawn side by side in a rectangular frame.
