The kanji 軸 軸 is a phono-semantic compound. The left side, 車 (くるま, kuruma), means "wheel" or "vehicle," representing movement or rotation. The right side, 由 (ゆう, yuu), is a phonetic component, lending the sound ジク jiku. Together, the character suggests a central "shaft" or "axis" around which a wheel turns, and thus it represents the central supporting element of a rotating object.
