Definitions:

Circular Runout

A tolerance that controls the uniformity of a feature's surface as it is rotated about a datum axis.

Eccentricity

Eccentricity refers to the degree to which a geometric shape’s center does not align with a reference axis or point, crucial in designing rotating parts to minimize imbalance.

Cylindricity

A form tolerance that defines how much a cylindrical feature's actual profile may deviate from a perfect cylinder.

Total Runout

Total runout is a tolerance that controls the total variation a surface can have when it is rotated around an axis or datum.
