Does the linear motion slide unit http://www.makeblock.cc/linear-motion-slide-unit-8mm-pair/ only allow for linear motion, or is it capable of rotational motion? i.e. can it twist back and forth as it slides along the rod?

This kind of linear motion unit is design for linear motion, it can twist back and forth, but it’s better to nou doing this too much
