Notes:

1. All metric machine screws have a trapezoidal thread form.

2. For loads of 25% to 100% of screw jack capacity, torque requirements are approximately proportional to the load.

3. Efciency values for standard grease lubricated worm gear box and lifting screw.

4. All C-Series screw jacks have grease lubricated gearbox and lead screw as standard.

5. Torque required to prevent the lead screw or lead nut from rotating if no anti-rotation device tted.

6. Radial force applied midway along worm shaft key at 90º to key.

7. Maximum transmittable torque through worm shaft, not through gear set.
