Specifications of 250 kN Capacity Screw Jack Metric Machine Screw
The specifications of 250 kn capacity screw jack metric machine screw include maximum load capacity, worm screw diameter and pitch, worm gear ratio, allowable maximum input power, torque and speed and overall efficiency etc.
1. Conditions: 20% running time/60 minutes or 30% running time/10 minutes, 20 °C ambient temperature. Maximum allowable input power 9kw, when your selection is exceed the maximum input power, the operational restrictions due to thermal limits. you will need to choose the bigger size screw jacks in order to allow effective heat dissipation.
2. Nm=input torque required, kW=input power required.
3. H=high ratio 10:1 (1mm stroke for one input turn), L=slow ratio 40:1 (0.25mm stroke for one input turn).
4. Selection of screw jacks using above figures should only be carried out in consultation with Jacton engineers.
