JWM Screw Jack Selection – 4 Parameters You Need to Provide


JWM Screw Jack Selection – 4 Parameters You Need to Provide

If you're buying a JWM screw jack for the first time, don't worry – you don't need to be an engineer. We just need 4 simple pieces of information to recommend the right model.

JWM threaded jack The 4 Parameters

1. Load Capacity (How much weight?)

Tell us the total weight you need to lift in kg or tons. JWM models range from 0.2 tons to 100 tons. If 

using multiple jacks, tell us how many – we'll calculate the load per jack.


2. Stroke (How far does it need to travel?)

This is the distance between the lowest and highest positions, in mm. Standard strokes vary by model.


3. Lifting Speed (How fast?)

Do you need slow, controlled movement or faster travel? Tell us your required speed in mm/min.


4. Mounting Preference (How will it be installed?)

Do you need the screw to move, or the nut to move? Upward or downward? We'll guide you through the 

options

Application scope:

1. Production equipment, used for lifting, shifting, tightening and turnover of production lines;

2. Equipment for fastening, lifting, and rotating metallurgical equipment;

3. Elevate machinery, flexible tools, and welding elevators for use in automotive manufacturing, etc.

4. Lifting devices for monocrystalline silicon and polycrystalline silicon grouting furnaces in the 

photovoltaic industry, as well as solar power generation tracking devices;

5. Aerospace, defense, military, astronomical telescopes, and other remote control devices;

6. The lifting device of the lifting device;

7. Shipbuilding, water conservancy, papermaking, food and warehousing, casting and other industries; 

Various implementation machinery for medical equipment, woodworking machinery, and food machinery;

8. Lifting devices on vertical and gantry machine tools.

Turbine ball screw elevator.

That's It!

Send us these 4 details, and our engineering team will select the right JWM model, check for critical speed limits, and recommend any accessories you may need.
