Looking into a ballscrew, not sure if I should buy. Help

What diameter and length of screw are you considering?

Sorry for the delay. Cell signal is not what I wish it would be and thus goes my efforts in a quick reply... :( Well I am unsure about exact diameter but I believe it to be about 1 Inch. Well here is the specs from the seller:
Travel: 96"

OAL: 105.63

Thread Length: 99.41

Thread Dia.: 40 mm

Thread Pitch: 40 mm RH

Nut Length: 3 3/4"

Nut Dia. (body): 2.870

Nut Dia. (flange): 4.580

Bearing Dia.: 1.181

Coupling Dia.: .9845

The motor kit I was looking into has 1 hp servos. Unsure at this point if I need to go larger. I know inertia, torque and other details have a big impact on the screw size. I am just unsure if my choice of electronic equipment is lacking. Some guidance is what I am looking for. Thank you all for your time.

What weird specs, some imperial some metric. Anyway that screw is 40mm dia nominal and weighs around 25kg and has massive inertia, you're going to need around 4Nm of torque just to spin the screw up to speed with any reasonable acceleration.

Why do you need such a big screw? That one will push some 4.3 tons along!
