Description:
Stainless steel Screw Jacks 25-Tons are suitable for application in corrosive environments. The Jack housing is casted in AISI 304 , Worm Screw is made in high tensile Stainless Steel, Worm Gear is made in high tensile Bronze. On the Trapezoidal Screw Jack the Work Screw is made in AISI 304. On the Ball Screw Jack the Work Screw is made in two parts, an internal ball screw made in hardened high tensile steel. Jacks are provided with special sealing to prevent internal parts from dust and water contamination.

Components Materials
1. 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 

Features
1. Upright or inverted units with maximum static load capacity 25 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 90mm diameter, 16mm pitch (single start trapezoidal screw thread).
4. Available in 10.667:1 and 32:1 ratios.
5. Custom travel lengths from 30mm to 5500mm. 
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.

Specifications
The specifications of 25 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.
2. Conditions: 20% running time/60 minutes or 30% running time/10 minutes, 20 ��C ambient temperature. Maximum allowable input power 4.8kw
3. H=high ratio 10.667:1 (1.5mm stroke for one input turn), L=slow ratio 32:1 (0.5mm stroke for one input turn).
4. Nm=input torque required, kW=input power required.
