Ball joints will work, but only if you spline the strut pieces to each
other so they can extend but not rotate relative to one another.

If you're using a motor, screw and nut in the strut, you have to keep
the top from spinning relative to the bottom. You can use U-joints and
a simple threaded strut, or ball joints and a more complicated strut.
I assume that the machine posted here uses simple threaded struts.
