Factors for The Screw Jack Performances Jun 26 , 2018

The production facilities can limit the stroke length 6m.
Further limits relate to buckling and critical speed of the acme screw.

The buckling load limit depends in turn on the way the screw is guided. Unguided screws have relatively low limits for the force and the stroke.  If the screw is fully guided buckling limits are generally not relevant.

Critical speed limits also depend on the screw fixing and the stroke length.  For screws with a supported end and strokes up to 1.5m, the critical speed will not be relevant.

When speed is high and the stroke is very long, the screw is easy to tremble and the screw jack uselife  also will be limited. And the guide is suggested to add when the speed is high.
