2.5 kN Cubic Mini Screw Jacks Specifications

1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. Static only (dynamic not permitted). Selection of screw jacks using these figures should only be carried out in consultation with our engineers. When your selection is made within the areas dark gray, you will need to reduce duty cycle or choose larger model screw jacks in order to allow effective heat dissipation.
2. Conditions: Duty cycle 20%/h or 30%/10min, 20 °C ambient temperature. 
3. Gear Ratios: H: high ratio, L: slow ratio.
4. Nm: Input torque required, kW: Input power required.
2.5 kN Cubic Mini Screw Jacks Design and Configurations
* US: Upright configurations, translating screw.
* IS: Inverted configurations, translating 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.
