The invention discloses a float roll system with both rectification and tension controlling functions. The float roll system comprises a machine frame, an input guiding idler roll, an output guiding idler roll, a float roll longitudinal position adjusting mechanism, a float roll, and a rectification and tension accurate adjusting mechanism, wherein the rectification and tension accurate adjusting mechanism comprises a rectification sensor, a tension sensor and a spherical motor. Thin film offset is detected as long as a thin film shifts on a feed surface, the runner of the spherical motor is driven to drive the float roll to swing on the thin film feed surface, and the float roll swings in an inverse direction due to the friction between the float roll and the thin film, so as to realize rectification; the runner of the spherical motor is driven to drive the float roll to rotate according to the comparative result between detected tension of the thin film and target tension, so that the axes of the runner and
