2.5 kN Cubic Mini Screw Jacks Specifications

1. Conditions: 20% running time/60 minutes or 30% running time/10 minutes, 20 °C ambient temperature. Maximum allowable input power 0.18kw, 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. H=high ratio 5:1 (0.8mm stroke for one input turn), L=slow ratio 20:1 (0.2mm stroke for one input turn).
3. Nm=input torque required, kW=input power required. 
4. Selection of screw jacks using above figures should only be carried out in consultation with Jacton engineers.
2.5 kN Cubic Mini Screw Jacks Design and Configurations
* US: Upright configurations, translating screw.
* IS: Inverted configurations, translating screw.

UK: Upright configurations, keyed anti-rotation screw.
IK: Inverted configurations, keyed anti-rotation screw.

2.5 kN Cubic Mini Screw Jacks Stroke
Example: 300 mm stroke, lifting screw travels 300 mm, then we will make the lifting screw length=stroke+housing height+screw end length. All lifting screws stroke is made following your requirements. Special lifting screws design, please consult us!!

2.5 kN Cubic Mini Screw Jacks Gear Ratios
* H: high gear ratio 1/5, lifting screw travels 0.8mm per turn of input shafts revolution.
* L: low gear ratio 1/20, lifting screw travels 0.2mm per turn of input shafts revolution.
Customized medium speed ratio 1/10, lifting screw travels 0.4mm per turn of input shafts revolution.

2.5 kN Cubic Mini Screw Jacks Lifting Screw End Conditions
Standard lifting screw end conditions such as top plate, clevis end, threaded end, plain end, spherical hinge, forked head. Can make lifting screw ends following your required. Before ordering, please send us your special design drawing of lifting screw ends.
