External re-circulation type ballscrew, consists of the screw shaft, the ball nut, the steel balls, the return tubes and the fixing plate. The steel balls are introduced into the space between the screw shaft and the ball nut. The balls are diverted from the ball tracks and carried back by the ball guide return tube forming a loop. Since the return tubes are located outside the nut body, this type is called the external re-circulation type ball screw.
