Circular run-out includes both radial and axial run-out variations during a full 360-degree rotation. Run-out Tolerance Limit (mm) Why Use the ISO 2768-mh Standard?

For nominal sizes below 0.5 mm, deviations must be specified individually . Circular run-out includes both radial and axial run-out
Because the second letter is "H", the part is subject to strict geometrical controls for features like Straightness, Flatness, Perpendicularity, and Symmetry. Nominal Length Range (mm) Geometric Tolerance (in mm) Up to Over Over Over Over Over Because the second letter is "H", the part
