How to calculate motor drive torque for ball screws

Drive torque is primarily influenced by the axial load on the screw and the screw's lead. F a = total axial force (N) P = lead (mm) η = efficiency of ball screw. The axial load is not only the process force (drilling, punching, etc.), but also includes the force required to move the load. Since most ball screw assemblies use profiled guide ...

TORQUE!!!!! | TDIClub Forums

That's tiny for bolts that size. But 15 Nm +90° seems (to my gut) to be a reasonable torque value for an 8x1.25 bolt. I just did a quick test using some 8x1.25 motorcycle hardware and a quality torque wrench and measured 15 Nm+90° to be 37 Nm, with zero measurable plastic deformation on that 20mm bolt.
