The Keypoint for Selection of Ball Screws

11 main points for the selection of ball screw specifications:

1. Determine the positioning accuracy.

2. Determine the lead of the screw by the motor and the speed requirements.

3. Check the nut size to determine the stroke and related data of the screw shaft end.

4. Determine the average axial force and speed through load and speed distribution (acceleration and deceleration).

5. Determine the preload by the average axial force.

6. The expected life, axial load, and rotational speed determine the dynamic rated load.

7. The basic dynamic rated load, lead, critical speed, and DmN value limit determine the outer diameter of the screw and the form of the nut.

8. The outer diameter, nut, preload and load determine the rigidity (machine design).

9, ambient temperature, the total length of the nut determines the thermal change and cumulative lead.

10. The lead screw rigidity and thermal displacement determine the pre-tension.

11. The machine's maximum speed, temperature rise time, and screw specifications determine the motor drive torque and specifications.
