The center around which something rotates?

Explanation:
Rotation happens around an axis, a straight line about which an object turns. The axis is the fixed line that the spinning parts move around—think of a wheel turning on its axle, where the axle is the axis. This is different from size terms: the diameter is the distance across a circle through its center, and the radius is half that distance. Centerline isn’t the standard term for the line of rotation in most cases. So the best description for the center around which something spins is the axis.
