1. If the two ends of the piston rod and the screw are installed in a fixed way, you can choose a piston rod with a relatively thin diameter. On the contrary, if the installation method of the screw and the shaft is relatively flexible, you can choose Piston rod with relatively thick diameter.
2. The lifting device is relatively small, so you can choose a piston rod with a relatively thin diameter. On the contrary, in an environment with a relatively large stroke, you need to choose a precision piston rod with a relatively thick diameter . The important thing is that due to the relatively long distance of the lifting device, the conflict force that occurs in the middle of the operation process is relatively large, and the conflict resistance force with a relatively thick diameter will be a little better.
3. The way of existence between the load center of gravity and the wire. If the two are repeated, a piston rod with a relatively thin diameter must be selected. Of course, if the two exist in a parallel manner, a relatively thick piston rod can be selected.
4. The screw rod and the bearing should be connected relatively parallel, and the parallelism of different equipment is also different. For some devices with relatively good parallelism, we can choose a precision piston rod with a smaller diameter.
