How many turns for a full stroke?

For any of **broken link removed**, how many turns it takes to excercise a full stroke?

They don't give the 'lead' of the main screw. The motor does say 48 steps per revolution(7.5* per step). You do know the shaft has to be kept from turning on that type don't you? There are two different type of linear steppers, free and captive screw. Some of the other brands give the lead of the screw in the data.
