The axis of the trapezoidal screw should be parallel to the axis of the supporting rail, and the bearing seats at both ends of the machine tool should be three o'clock and one line; when installing the nut, try to close the support bearing as much as possible. The outer diameter of the auxiliary case should be less than 0.1-0.2mm than the bottom diameter of the screw; the auxiliary cover should rely on the screw thread shoulder in the use; when unloading, do not use it too hard to avoid the nut damage; avoid impact and eccentricity when installing the installation hole.
