The balls roll between the spiral grooves of the lead screw and nut for efficient and precise linear motion. The following is a detailed introduction to the Ball Screw nut ball rolling method. Ball Screws are composed of screws, nuts, balls, pre-pressed sheets, reversers, and dust preventers, among others. The spiral grooves on the screw are matched to the spiral grooves inside the nut, and the balls roll between these grooves, realizing the linear motion of the nut when the screw rotates. There are two main types of ball circulation: external circulation and internal circulation: in the external circulation system, the ball is discharged from one end of the nut through an elbow or cannula, and returns to the other end through an external pipe.
