When using the tail suspension intermediate swing installation, the position of the connecting pin at the top of the piston rod is in the same direction as the position of the mounting shaft; when using the intermediate shaft pin swing installation, in addition to paying attention to the position of the connecting pin at the top of the piston rod, you should also pay attention to the verticality of the magnetic rodless cylinder axis line and the shaft bracket. At the same time, within the range that does not cause jamming, the swing shaft bracket should be as close to the root of the swing shaft as possible.
