Two 15-tons stainless steel translating machine screw jacks are connected in series by a stainless steel drive shaft and geared couplings. All metric stainless steel machine screws have a trapezoidal thread form, single start as standard. Other screw lead options are available on request. Based on operating capacity for loads of 25% to 100% of screw jack capacity, torque requirements are approximately proportional to the load. Efficiency values for standard grease lubricated worm gear box and lifting screw. Ideally suited to perform in harsh environments (wet/dusty/dirty). Corrosion resistant models can be used in chemically adverse environments.

Main Features
1. Upright or inverted units with maximum static load capacity 15 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 58mm diameter, 12mm pitch (single start trapezoidal screw thread).
4. Available in 8:1 and 24:1 ratios.
5. Custom travel lengths from 20mm to 3500mm. 
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.

The specifications of 15-tons stainless steel translating 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 2.6kw
3. H=high ratio 8:1 (1.5mm stroke for one input turn), L=slow ratio 24:1 (0.5mm stroke for one input turn).
4. Nm=input torque required, kW=input power required.

How to Correctly Select a Complete Part Number and Place an Order

1. Model Number

- JSS-15T, Maximum static load capacity 15 tons.
- Stainless Steel Self-locking Trapezoidal screw diameter 58mm, pitch 12mm.  
Important Note: Under compression load, screw jack with long stroke, must check the permissible buckling load. 

2. Stainless Steel Jack Configuration and Jack Designs
- US
: Upright mount, Translating Screw Design.
- IS: Inverted mount, Translating Screw Design.
- UR: Upright mount, Rotating Screw Design.
- IR: Inverted mount, Rotating Screw Design.
- UK: Upright mount, Anti-rotation Keyed Screw Design.
- IK: Inverted mount, Anti-rotation Keyed Screw Design.

Important Note: 
The lifting screw of stainless steel Translating Screw Jack (US or IS) must be attached to the guided load which prevents the lifting screw from rotating. To add the linear guides, linear rails or rolls are recommended.
- Important Note: If your application involves a load which is unattached, unguided or the load is free to rotate and not translate, then a stainless steel Anti-rotation Keyed Screw Jack (UK or IK) are required to prevent lifting screw rotation (not recommended).
- Important Note: Double Lead Screw is not self-locking, may lower under load. Brake motors or external locking systems are recommended. 
- Available in Double Clevis stainless steel Screw Jack, and Trunnion Mounting stainless steel Screw Jack (pivoting load). 

3. Stroke
- Stroke is travel expressed in millimeter(mm) or inches and not the actual screw length.  

4. Worm Gear Ratio
- H: High ratio 8:1, one turn of input, travel length 1.5mm
- M: Medium ratio 12:1, one turn of input, travel length 1.0mm
- L: Slow ratio 24:1, one turn of input, travel length 0.5mm
- Customize the worm gear ratios.

5. Stainless Steel Screw End Conditions
- Standard stainless steel Screw End Conditions: top plate(load pad), clevis end(male clevis), plain end, threaded end. Also rod end, and fork head(female clevis) are available. Custom screw ends are acceptable.
