Types of Screw Jack System:
In type, worm wheel rotations occur on the lead screw, which provide linear movement. If the end of the lead screw is not accurately connected, the lead screw moves due to friction between the screw threads.
The lead screw provides rotation to avoid turning. It is important to use it when the lead screw is not connected with the load.
The applications that have different screwjack connections with mutual loads, where encrypted and non-encrypted transmission screws are used
- This type comes with a lead screw connected with a worm wheel that provides rotation of the worm wheel to provide rotation of the lead screw.
- In a result, move the nut with the lead screw during the nut connection with the load.
- The other name of this type is worm screw, which comes with a threaded screw known as a worm and a toothed wheel.
- The worm comes with a helical thread that configures with gear teeth, providing rotational movement of the worm for gear rotation.
- This type of screw jack is used for providing minimal speed and high torque, so it is used in the vehicle industry, machines, and conveyors.
- They prefer it since it is a strongly fixed component, and the self-locking feature, since it has high friction between worm and gear teeth, avoids back driving.
- Ballscrew jack uses a ball screw system for converting rotary motion into linear motion, which helps to get effective vertical or horizontal lift for high loads.
- It comes with a threaded screw shaft having ball bearings in a proper casing.
- Due to screw rotation, ball bearings move over the screw’s helical groove, converting rotational motion into linear motion.
- This module has high efficiency, low friction, and high accuracy.
- It is used in vehicles and the manufacturing industry and provides reliable high-load lifts.
Advantages of Screw Jack System:
Simple structure:
Due to its simple structure, the screw jack does not require a complex hydraulic or pneumatic system, making maintenance work more convenient and low in maintenance costs.
Strong stability:
Because the structural design of the screw jack is very stable, it can carry a relatively large load and maintain stability during long-term use, and is not prone to failure.

No external power required:
The screw jack does not require electricity or air source support, and the user only needs to manually rotate the screw, so it can be used in an environment without power or air source, which is very suitable for outdoor or emergency situations.
Easy to carry:
Compared with hydraulic jacks, screw jacks have significant advantages in portability and size. Its exquisite design, easy to store and carry, is particularly suitable for car owners to carry with them as a vehicle emergency tool.
