†Speed/Force correlating equations:

1Axial Force = Ffriction + Facceleration + Fgravity

Ffriction = (Weight)(0.09)

Facceleration = (Weight)(Acceleration) / Accel. of gravity

Fgravity = 0 for horizontal application and 1 Weight for vertical application

2(Axial Force)(Screw Lead) Torque = (0.393)(Screw Efficiency)
