This ball screw came from a manufacturer. In its catalogue there is a technical part where friction and torque computation are indicated. Due to the geometry of the contact ball-screw and internal pre-loading, different from source to source, it will be better to look in the catalogue.

Where is torque applied to screw or nut,

is linear force applied,

is ball screw lead, and

is ball screw efficiency.
