Stainless Steel Machine Screw Jacks 2.5 Tons 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.
Components Materials1. Lifting screw: stainless steel 304
2. Input worm shaft: stainless steel 304
3. Worm gear or travelling nut: bronze
4. Housing: stainless steel 304
5. Bearings: bearing steel as standard. If underwater application, required stainless steel 304 bearing
6. Covers of input worm shaft: stainless steel 304
7. Top covers of housing: stainless steel 304
8. Protective tube: stainless steel 304
9. Locking screws: stainless steel 304
10. Lifting screw ends (top plate, clevis end, threaded end, plain end, fork end or rod end): stainless steel 304
11. Motor flanges: stainless steel 304
Features1. 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 (travelling screw jacks), keyed lifting screws for anti-rotation, and rotating lifting screws with traveling nut (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.
SpecificationsThe specifications of 2.5 ton Stainless Steel Worm Gear Machine Screw Jacks include maximum load capacity, worm screw diameter and pitch, worm gear ratio, allowable maximum input power, torque and speed and overall efficiency 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.
