How many turns for the full stroke?

For any of these linear actuators, where to look at to know how many turns it takes to excercise the whole stroke?

 

I see step angle and steps/rev but nothing in the lead of the screw? Assuming a leadscrew.

It's in a different datasheet or page: http://www.farnell.com/datasheets/526510.pdf
48 steps per revolution

Quite fine resolution, .096"/rev and .048"/rev, or 10.4 rev/" and 20.8 rev/".

Aha, linear travel per step. That's it.

Gracias to you both.

PD: as usual, once you know, it is easy.
