2.5 Tons Stainless Steel Machine Screw Jacks are typically used in harsh or corrosive environments or those with a regular wash down requirement. Industries such as Marine, Water Treatment, Nuclear, Food Processing, Offshore, Pulp and Paper use stainless steel screw jacks. For each application, variants with different material grades or plated components can be used, tailoring the product for the specific application and budget.
1. Upright or inverted units with maximum static load capacity 2.5 ton in tension or compression.
2. With higher ratios are inherently self-locking and will hold the loads without creep as long as the screw jack is not subject to vibration.
3. Lifting screw with 30mm diameter, 6mm pitch (single start trapezoidal screw thread).
4. Available in 6:1 and 24:1 ratios.
5. Custom travel lengths from 10mm to 2000mm.
6. Translating lifting screws (stainless steel travelling screw jacks), keyed lifting screws for anti-rotation (stainless steel keyed screw jacks), and rotating lifting screws with traveling nut (stainless steel travelling nut screw jacks) as the standard configurations.
7. Worm screw (input shaft) is rotated by a handwheel with handle (manually operated screw jack) or by a gear motor (electrically operated screw jack).
8. Can be applied either individually use or in tandem or in multiple arrangements for exactly synchronized lifting system, linked by connecting shafts, bevel gears and couplings etc.

1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. 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 shaded dark gray, you will need to reduce duty cycle or choose the bigger size screw jack in order to allow effective heat dissipation.
