An article on learning the selection of ball screw

Firstly, take a look at the requirements of your device and clarify these parameters: accuracy, load, stroke, speed that requires automation, etc.

① Precision: The ball screw has grinding rods and rolling rods, which have different precision and higher grinding accuracy. Therefore, if the equipment requirements are high, the grinding rod should be selected.

② Load: The larger the diameter of the screw, the better its rigidity, and the greater the load it can withstand.

③ Lead: determines the speed of carrier movement, and the lead of the screw refers to the distance the screw rotates one turn to move the nut. The larger the value, the faster the speed.

④ Pre pressing: refers to the pre tightening force between the nut and the screw, and the pre pressing is adjusted by selecting steel balls with different diameters.

⑤ The flange installation hole spacing of the nut should match the equipment.
