A ball nut is a mechanical transmission element composed of a screw, balls, a nut, and a support. The screw is a threaded part that transmits motion through rotation. The balls are the transmission medium of the thread, rolling along the screw's axis to transmit motion. The nut is an annular washer between the balls and the screw, serving to transmit force and keep the balls on their tracks. The support is the supporting structure of the nut, used to support it and maintain its stability and positioning accuracy during movement.
