Why does the ball not fly off the fan? It is because of Bernoulli's principle. The fast-moving air, which carries the ball into the air, is at a lower pressure than the air surrounding the ball. As the ball is trying to fall off the fan, this surrounding higher-pressure air pushes the ball back into the area of lower pressure above the fan.

As the screw or nut rotates, the balls are deflected by the deflector into the ball return system of the nut and they travel through the return system to the opposite end of the ball nut in a continuous path. The balls then exit from the ball return system into the ball screw and nut thread raceways continuously to recirculate in a closed circuit.
