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 E-Series screw jacks have grease lubricated gearbox and lead screw as standard.
5. For performance data for Anti-Backlash, Anti-Rotation (keyed) and other variants please consult corresponding catalogue.
