Linear actuator shaft rotation?

I’m looking to automate a procedure with a linear actuator, possibly LACT10P-12V-20.
My understanding is: unless otherwise stated, this is the properties of linear actuators based on worm gear: when a load is applied, and there is nothing to prevent the shaft from rotating, it will rotate instead of lifting the load.
I would like to know if that is the case with your linear actuators, since the load cannot be kept from rotating in our application.


With the linear actuators we carry, the shaft is prevented from rotating, and it will move linearly even with nothing else connected. However, you should know that the shaft cannot support much torque about its axis, since it is simply screwed on to the moving part and can be easily unscrewed.
