The torque required to achieve this force with a dry bolt is calculated to 2022 Nm. If the load on a screw jack is 50000 lb, the lever-arm is 20 inches and the pitch equals 1/8 inches - the effort force can be estimated to F = ((50000 lb) (1/8 in)) / (2 π (20 in)) = 49.8 lb The torque acting on the screw can be calculated Axial Bolt "Clamp" Force Most commonly used mounting setup. This is can be dependent on a number of factors, but is largely a function of the preload force, the force exerted in compressing the bolt, and the tension force, the force exerted in pulling the bolt apart. This calculator will calculate torque given the lead screw

Torque(raise) = F*Dm/2*(L+u*PI*DM)/(PI*Dm-u*L), Torque(lower)= F*Dm/2*(L-u*PI*DM)/(PI*Dm+u*L). Calculated values are approximate. A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. Axial Load (N) Lead (mm) Preload Reset Calculate. Your first equation, for effort, is Feffort=Sf+Load2∗π∗(RP)∗Se where, 1. Torque = Force x Distance = (Rotational Force acting on a ball bearing) x (radius of ballscrew) So you can calculate the rotational vector component of force based on torque and the radius of the ballscrew.
