WebJan 26, 2024 · Circular runout, commonly known as just ‘runout’ is a 2D measure of a circular profile in relation to a datum axis. It inspects how well a circular cross-section conforms to a perfect circle much like circularity. The tolerance zone is between the outer and inner rings on a 2D plane. WebMay 11, 2007 · Circularity simply means how round something is. Circular runout is how round relative to another feature (s). Roundness (circularity) is to itself and never to another diameter.
